I just want to say that your method worked for me on my win 10 Though I later got a. All the same thanks for being a solution to our generation. From my little home here in Africa. Another extremely grateful guy here, and likewise the company I work closely with. Thank you, thank you, thank you! I got it. You batch file worked. However I needed to remove the drive identification part and hardcode the drive letter. Great article sir! It worked almost perfectly.
I did not have the Windows 10 media as I upgraded from Windows 7. It took few hours to download the Windows 10 installation files and create the actual ISO file. And extract it from there? Thank you for your help! I tried so many different things to install this. NET Framework… none of them worked, and I badly needed the 3. Your guide was the only solution and it was also very easy to follow for a clumsy user like me… thank you so much!
Installation via Command Prompt was very quick. Thanks for that great tip. This article saved me lots of headaches and I could get to work finally. Winaero is one of the best sites for Windows related stuff. Thanks alot, worked excellent on Win 10 v Anniversary Edition.
Control Panel-add windows features still wanted the internet, this worked offline. A reply would be much appreciated! Net framework 3. Superb work I really appreciate. Dear did you prepared any script for windows 8. I really liked your work and I want or windows 8. Thank you so much. I have lost hours trying to get this done. Yo,Thanks For sharing this article it really works!! Can i use this in a youtube tutorial please? You are awesome. I try everything and finally its worked. Again thx man.
Love you. Thank you! Worked perfectly. Thank you. The only think that worked for me. Thank you a lot. Please help…. Thanks for batch file. In case someone install x64 bit version of Windows like me! You cannot service a running bit operating system with a bit version of DISM. It will use Dism. I had to change the file search for to determine which drive to use to look for install.
Did work though, thanks. The drive letter must be changed where the Windows 10 installer is located. This is an example:. Check that the installation and activation of. NET 2. Usually win 10 comes by default. NET 4 and programs created in lower version willnot work so you need to install it and the way shown above is very nice, just run the above patch should run successfully. Great work. Only thing is you do not need the whole bootable drive. This works if u only have the sxs folder with NetFX3.
Hi Sergey, unfortunately, it did not work for me. NET Framework should be installed any ideas please? Transaction support within the specified resource manager is not started or was shut down due to an error. On 3 separate machines updated to Windows 10 to the current July updates I was not able to install Microsoft. We had IE 11 set as the default browser, once Edge was set as the default browser Windows Updates applied.
Let me correct myself, it was not setting Edge as the default browser that resolved my issue, although I would not be surprised if Microsoft got to that point eventually since they are moving away from IE The issue was resolve by uninstalling Windows Update KB When removed all 3 machines did update event with IE 11 as default browser on one of them. Not working on brand new clean install of Windows 10 Perfect explanation and instructions.
Worked successfully. Really appreciate your help. One of our apps still demands. Long story short is that this app had to be re-installed for the user, failed because this time it could not find. I hunted down the Win 10 DVD that came with those workstations, copied your command and installed. Your guide laid out just what I needed to do. Kia kaha! Hello Sir, I downloaded the dot net framework 3. Please need your help. Weitere Informationen finden Sie in der Protokolldatei.
I also failed with the downloaded batch file. Note I have only a install. In the right pane, double click on Specify settings for optional component installation and component repair. Then tried your scrip again. No errors but Net Framework would not install. I just got enabling features and then nothing no percentage install or anything. I wonder if the install. EP Open the batch file and try replacing install. Dude seriously thank you so much! I needed this for so many things, work and leisure.
Script works with Win 10 x64 Home Build ! A Billion Thanks! Good Work. Net Framework 3. Thanks for great advise. Thanks a ton!!! I spent 5 or so hours installing, updating, fixing this thing, and nothing worked. Once I followed your advice and boom it worked.
You are appreciated. Your email address will not be published. Skip to content Advertisement. Support us Winaero greatly relies on your support. Because it will start to download. Just try yourself. Thanks Sergey, I have been at wits end trying to install.
Regards Trevor. It worked for me , using your extracted files. Am most grateful. I try your thing and it give me error 2 and show me where is the dsim file.
Not everyone has the laxury of being connected always. It just saved me a lot of time. I tried multiple other methods but nothing was working for me. Never even thought of checking the win10 media! I have cab file for x86 but i dont have cab file for x Help me please…. Hmm, thank you Brian. I will look closer what is wrong with build No operation was performed.
For more information, review the log file. Thank you so much for this! I have been trying for so long to install. After 2 hours of research this right here worked for me. Windows 10 Pro. I have exactly your issue. Anyone else come across this? Found a way forward? Seems to be broken for now. Net 3. SO just fyi.. I manually retyped the dism….
Download the official ISO image. It is available for free from Microsoft. I was restricted to so many apps till I found this batch file. Thumps up man! Helps alot of ppl.
EXE: Got the collection of providers. This property is used to locate the java executable and should be configured to point to the home directory of the Java SE 8 installation. Java SE Development Kit 1.
Apache Maven 3. Extract the files in the directory of your choice. The data folder contains all the working and temporary files for Karaf. If you want to restart from a clean state, you can wipe out this directory, which has the same effect as using the clean option to the Karaf start. You can also manage Apache Karaf as a system service see System Service section.
Apache Karaf stores all previously applications installed and changes that you did in the data folder. You can plug your IDE to define breakpoints, and run step by step. For instance, to set the minimum and maximum memory size for the JVM, you can define the following values:. Even if you start Apache Karaf without the console using server or background modes , you can connect to the console.
This connection can be local or remote. It means that you can access to Karaf console remotely. You can use --help to get details about the options:. Actually, client is a SSH client. More generally, you can use the shutdown command on the Apache Karaf console that works for all cases.
The shutdown command asks for a confirmation. If you want to bypass the confirmation step, you can use the -f --force option:. The shutdown command accepts a time argument. With this argument, you can define when you want to shutdown the Apache Karaf container.
The time argument can have different formats. First, it can be an absolute time in the format hh:mm, in which hh is the hour 1 or 2 digits and mm is the minute of the hour in two digits. The word now is an alias for 0.
The shutdown command accepts the -r --restart option to restart Apache Karaf:. The SystemMBean provides different attributes and operations, especially operations to halt or reboot the container:.
The time format is the same as the time argument of the shutdown command. In the previous chapter, we saw the different scripts and commands to start, stop, restart Apache Karaf. Instead of using these commands and scripts, you can integrate Apache Karaf directly in your operating system service control using:. The "Service Wrapper" correctly handles "user log outs" under Windows, service dependencies, and the ability to run services which interact with the desktop. It also includes advanced fault detection software which monitors an application.
The "Service Wrapper" is able to detect crashes, freezes, out of memory and other exception events, then automatically react by restarting Apache Karaf with a minimum of delay. It guarantees the maximum possible uptime of Apache Karaf. Apache Karaf Service Wrapper is an optional feature. You have to install the "Service Wrapper" installer first. You have a complete explanation and list of system commands to perform to integrate Apache Karaf in your systemV:. Karaf also supports the systemd service, so you can use systemctl instead of a SystemV based service:.
If you want to add org. Finally, after restart your session or system you can use launchctl command to start and stop your service. In this file, you can configure the different environment variables used by Apache Karaf. The Service Wrapper installer automatically populates these variables for you during the installation using wrapper:install command. For instance:. The next index to use is By using the "Service Script Templates", you can run Apache Karaf with the help of operating system specific init scripts.
As opposed to the Service Wrapper, the templates targeting Unix systems do not rely on 3rd party binaries. The karaf-service. The utility karaf-service. Installation of Apache Karaf as windows service is supported through winsw. The commands have a scope and a name.
For instance, the command feature:list has feature as scope, and list as name. You can note that you enter in a subshell directly by typing the subshell name here feature. You can "switch" directly from a subshell to another:. By default, you have:. You can also provide the new completion mode that you want. When you type the tab key, whatever in which subshell you are, the completion will display all commands and all aliases:. If you type the tab key on the root level subshell, the completion will display the commands and the aliases from all subshells as in GLOBAL mode.
However, if you type the tab key when you are in a subshell, the completion will display only the commands of the current subshell:. If you type the tab key on the root level, the completion displays the subshell commands to go into a subshell , and the global aliases. Once you are in a subshell, if you type the TAB key, the completion displays the commands of the current subshell:.
But you can also use the help command to get details about a command or the man command which is an alias to the help command. You can also use another form to get the command help, by using the --help option to the command.
The shell:alias command creates a new alias. For instance, to create the list-installed-features alias to the actual feature:list -i command, you can do:. You can pipe the output of one command as input to another one. So you can use head instead of shell:head. Again, you can find details and all options of these commands using help command or --help option. You can create the list yourself as in the previous example , or some commands can return a list too.
It means that you can use methods available in the ArrayList objects like get or size for instance :. We can note here that calling a method on an object is directly using object method argument. The spaces are important when writing scripts.
For instance, the following script is not correct:. You can also name your script with an alias. Actually, the aliases are just scripts. Apache Karaf supports a complete remote mechanism allowing you to remotely connect to a running Apache Karaf instance. More over, you can also browse, download, and upload files remotely to a running Apache Karaf instance. For security reason, by default, karaf user is disabled.
To allow the logon, you have to have an user. This remote console provides all the features of the "local" console, and gives a remote user complete control over the container and services running inside of it.
As the "local" console, the remote console is secured by a RBAC mechanism see the Security section of the user guide for details.
In addition to the remote console, Apache Karaf also provides a remote filesystem. The default value is 0. You can bind on a target interface by providing the IP address of the network interface. This file stores the private key of the SSHd server. Note that Karaf does not use this property to encrypt the private key when generating it, only for reading external keys that are already encrypted. Also note that specifying a hostKeyPassword might require installing the BouncyCastle provider to support the desired encryption algorithm.
See the [Security section security] of this user guide for details. The possible values are , , , or The default value is The default value is RSA. You can do it with:. Apache Karaf itself provides a SSH client. When you are on the Apache Karaf console, you have the ssh:ssh command:. Thanks to the ssh:ssh command, you can connect to another running Apache Karaf instance:. You can also provide directly a command to execute using the command argument.
For instance, to remotely shutdown a Apache Karaf instance:. For instance, to retrieve the karaf. You can also use a graphic client like filezilla , gftp , nautilus , etc. The Apache Karaf system folder is the Karaf repository, that uses a Maven directory structure. Using Apache Maven, you can populate the system folder using the deploy:deploy-file goal. It means that applications can use any logging framework, Apache Karaf will use the central log system to manage the loggers, appenders, etc.
This file is a standard Log4j configuration file. A stdout console appender is pre-configured, but not enabled by default. This appender allows you to display log messages directly to standard output. The out appender is the default one. The sift appender is not enabled by default. This appender allows you to have one log file per deployed bundle.
You can edit this file at runtime: any change will be reloaded and be effective immediately no need to restart Apache Karaf. This files configures the Log Service used by the log commands see later. Before Karaf starts proper logging facilities pax-logging , it may configure java.
Standard Java logging is used initially by the Main class and org. Lock implementations. In order to configure the logging level, please set the system property karaf. And because org. For example, setting karaf. You can also display the log entries from a specific logger, using the logger argument:. By default, all log entries will be displayed. It could be very long if your Apache Karaf container is running since a long time. You can limit the number of entries to display using the -n option:.
You can disable the coloring using the --no-color option. You can also change the pattern dynamically for one execution using the -p option:. As for log:display command, the log:exception-display command uses the rootLogger by default, but you can specify a logger with the logger argument. The logger argument accepts the ALL keyword to display the log level of all logger as a list. The log:log command allows you to manually add a message in the log.
By default, the log level is INFO, but you can specify a different log level using the -l option:. You can specify a particular logger using the logger argument, after the level one:. The purpose of the DEFAULT keyword is to delete the current level of the logger and only the level, the other properties like appender are not deleted in order to use the level of the logger parent loggers are hierarchical.
It means that, at runtime, the my. So, both my. The log:tail is exactly the same as log:display but it continuously displays the log entries. As this operation supports the ALL keyword, it returns a Map with the level of each logger. You can use filters on an appender. Filters allow log events to be evaluated to determine if or how they should be published. The DenyAllFilter org. DenyAllFilter drops all logging events. You can add this filter to the end of a filter chain to switch from the default "accept all unless instructed otherwise" filtering behaviour to a "deny all unless instructed otherwise" behaviour.
The LevelMatchFilter org. LevelMatchFilter is a very simple filter based on level matching. If there is an exact match between the value of the LevelToMatch option and the level of the logging event, then the event is accepted in case the AcceptOnMatch option value is set to true. Else, if the AcceptOnMatch option value is set to false , the log event is rejected. The LevelRangeFilter org. LevelRangeFilter is a very simple filter based on level matching, which can be used to reject messages with priorities outside a certain range.
The StringMatchFilter org. StringMatchFilter is a very simple filter based on string matching. For instance, you can use the f1 LevelRangeFilter on the out default appender:. A nested appender is a special kind of appender that you use "inside" another appender. It allows you to create some kind of "routing" between a chain of appenders.
The AsyncAppender org. AsyncAppender logs events asynchronously. This appender collects the events and dispatch them to all the appenders that are attached to it. The RewriteAppender org. RewriteAppender forwards log events to another appender after possibly rewriting the log event. For instance, you can create a AsyncAppender named async and asynchronously dispatch the log events to a JMS appender:.
Sometime, appenders can fail. For instance, a RollingFileAppender tries to write to the filesystem but the filesystem is full, or a JMS appender tries to send a message but the JMS broker is not there.
This is the purpose of the error handlers. Appenders may delegate their error handling to error handlers, giving a chance to react to the errors of the appender. The OnlyOnceErrorHandler org. The error message is printed on System.
This policy aims at protecting an otherwise working application from being flooded with error messages when logging fails. The FallbackErrorHandler org. FallbackErrorHandler allows a secondary appender to take over if the primary appender fails. You can define the error handler that you want to use for each appender using the errorhandler property on the appender definition itself:.
By default, Apache Karaf provides a special stack trace renderer, adding some OSGi specific specific information. In the stack trace, in addition of the class throwing the exception, you can find a pattern [id:name:version] at the end of each stack trace line, where:. For instance, in the following IllegalArgumentException stack trace, we can see the OSGi details about the source of the exception:.
The easiest way to do that is to package your appender as an OSGi bundle and attach it as a fragment of the org. Copy your bundle in the Apache Karaf system folder. You have to restart Apache Karaf with a clean run purging the data folder in order to reload the system bundles. You can use the following env variable:. The configuration file names follow the pid.
Default and alternate values can be defined for them as well using the same syntax as above. Usually secrets for example when provided by Kubernetes will surface as files in a location. By default, the location is etc folder. However, you can point to any folder. The file contents are opaque and contain the secret value as-is. To use content of a secret file in a configuration property, you can do:. Default is true. Only files matching the pattern will be loaded.
Default value is. Default value is meaning that Apache Karaf "re-loads" the configuration files every second.
If true , Apache Karaf polls the configuration files as soon as the configuration service starts. The higher this value, the more verbose the configuration service is. Apache Karaf persists configuration using its own persistence manager in the case of when available persistence managers do not support that.
Without the query argument, the config:list command display all configurations, with PID, attached bundle and properties defined in the configuration:. All changes that you do in configuration edit mode are stored in your console session: the changes are not directly applied in the configuration. It allows you to "commit" the changes see config:update command or "rollback" and cancel your changes see config:cancel command.
The config:property-list lists the properties for the currently edited configuration. The config:property-set command updates the value of a given property in the currently edited configuration. For instance, to change the value of the size property of the previously edited org. You can use config:property-set command outside the configuration edit mode, by specifying the -p for configuration pid option:.
The config:property-append is similar to config:property-set command, but instead of completely replacing the property value, it appends a string at the end of the property value. For instance, to add 1 at the end of the value of the size property in org. You can use the config:property-append command outside the configuration edit mode, by specifying the -p for configuration pid option:.
The config:property-delete command deletes a property in the currently edited configuration. For instance, you previously added a test property in org.
To delete this test property, you do:. You can use the config:property-delete command outside the configuration edit mode, by specifying the -p for configuration pid option:. Thanks to that, you can "commit" your changes using the config:update command. The config:update command will commit your changes, update the configuration, and if possible update the configuration files.
For instance, after changing org. On the other hand, if you want to "rollback" your changes, you can use the config:cancel command. It will cancel all changes that you did, and return to the configuration state just before the config:edit command. The config:cancel exits from the edit mode. For instance, you added the test property in the org.
The config:delete command completely deletes an existing configuration. You can delete the my. The config:meta command lists the meta type information related to a given configuration. It allows you to get details about the configuration properties: key, name, type, default value, and description:. The main information provided by a feature is the set of OSGi bundles that defines the application.
Such bundles are URLs pointing to the actual bundle jars. For example, one would write the following definition:. One of these is the Maven URL handler, which allow reusing maven repositories to point to the bundles.
As we can use file: as protocol handler to deploy bundles, you can use the following syntax to deploy bundles when they are located in a directory which is not available using Maven. In addition to being less verbose, the Maven url handlers can also resolve snapshots and can use a local copy of the jar if one is available in your Maven local repository.
The org. Full reference of org. These can be treated as read-only repositories, as nothing is written there during artifact resolution. This local repository is used to store artifacts downloaded from one of remote repositories, so at next resolution attempt no remote request is issued.
By default, snapshots are disabled. For example. Full configuration of org. This however may be cumbersome in some scenarios. This command shows a quick summary about current org. It may be implicit, explicit or default. We can also see whether the value was configured in PID or in settings. This option may be used only by user with admin role. This command displays all configured Maven repositories - in a much more readable way than the plain config:proplist --pid org. It uses the settings.
When dealing with the settings. In order to use encrypted repository or http proxy passwords inside settings. The above usage simply prints the encrypted master password. We can however make this password persistent. This will result in the creation of a new settings-security. These are read-only local repositories that are simply queried before performing any remote access.
These are well-known Maven remote repositories - usually accessible over http s protocol. In the above example, a new settings. The reason is that although a new repository itself was added to org. After creating a repository, it may be deleted using maven:repository-remove command or changed maven:repository-change command. All the options are the same as in maven:repository-add command. When removing a repository, only -id and possibly -d options are needed. When accessing remote repositories using org.
It has to be done in settings. It automatically does a copy of the existing settings. Apache Karaf supports the provisioning of applications and modules using the concept of Karaf Features. By provisioning an application, it means to install all modules, configuration, and transitive applications. In OSGi, a bundle can depend on other bundles.
So, it means that to deploy an OSGi application, most of the time, you have to firstly deploy a lot of other bundles required by the application. So, you have to find these bundles first, install the bundles. Again, these "dependency" bundles may require other bundles to satisfy their own dependencies. More over, typically, an application requires configuration see the [Configuration section configuration] of the user guide.
So, before being able to start your application, in addition to the dependency bundles, you have to create or deploy the configuration. When you install a feature, Apache Karaf installs all resources described in the feature. It means that it will automatically resolve and install all bundles, configuration, and dependency features described in the feature.
The feature resolver checks the service requirements, and installs the bundles providing the services matching the requirements. The default mode enables this behavior only for "new style" features repositories basically, the features repositories XML with schema equal or greater to 1.
Additionally, a feature can also define requirements. In that case, Karaf can automatically install additional bundles or features providing the capabilities to satisfy the requirements.
By default, the feature service is able to detect bundles which need to be refreshed. For instance, a bundle has to be refreshed:. Then bundle A has to be refreshed to use the new version of the package.
Then, bundle A has to be refreshed to actually use the package. This is kind of "cascading" refresh. Some users might be concerned about this refresh behavior, and prefer to manage refresh "by hand". By default, autoRefresh is true. Using false will disable auto refresh performed by the Karaf features service.
This file contains the description of a set of features. A features descriptor is named a "features repository". Before being able to install a feature, you have to register the features repository that provides the feature using feature:repo-add command or FeatureMBean as described later. For instance, the following XML file or "features repository" describes the feature1 and feature2 features:.
We can note that the features XML has a schema. The feature1 feature is available in version 1. If you install the feature1 feature using feature:install or the FeatureMBean as described later , Apache Karaf will automatically install the two bundles described. The feature2 feature is available in version 1.
If the version attribute is not specified, Apache Karaf will install the latest version available. You can restart Apache Karaf, the previously installed features remain installed and available after restart. To prevent this behaviour, you can specify features as boot features.
A boot feature is automatically installed by Apache Karaf, even if it has not been previously installed using feature:install or FeatureMBean. Thanks to the features lifecycle, you can control the status of the feature started, stopped, etc.
Each line in the file defines one override. If no range is given then compatibility on the micro version level is assumed. So for example the override mvn:org. The start-level attribute insures that the myproject-dao bundle is started before the bundles that use it.
Instead of using start-level, a better solution is to simply let the OSGi framework know what your dependencies are by defining the packages or services you need. It is more robust than setting start levels. You can simulate the installation of a feature using the -t option to feature:install command.
You can install a bundle without starting it. By default, the bundles in a feature are automatically started. A feature can specify that a bundle should not be started automatically the bundle stays in resolved state.
A bundle can be flagged as being a dependency, using the dependency attribute set to true on the bundle element. When the my-project feature will be installed, the other feature will be automatically installed as well. A prerequisite feature is a special kind of dependency. If you add the prerequisite attribute to dependant feature tag then it will force installation and also activation of bundles in the dependant feature before the installation of the actual feature.
This may be handy in the case that bundles enlisted in a given feature are not using pre installed URLs such as wrap or war.
The name attribute of the config element corresponds to the configuration PID see the [Configuration section configuration] for details. The installation of the feature will have the same effect as dropping a file named com. Instead of using the config element, a feature can specify configfile elements. Instead of directly manipulating the Apache Karaf configuration layer as when using the config element , the configfile element takes directly a file specified by a URL, and copy the file in the location specified by the finalname attribute.
If the file is already present at the desired location it is kept and the deployment of the configuration file is skipped, as a already existing file might contain customization. This behaviour can be overriden by override set to true.
A feature can also specify expected requirements. The feature resolver will try to satisfy the requirements. For that, it checks the features and bundles capabilities and will automatically install the bundles to satisfy the requirements. The requirement specifies that the feature will work by only if the JDK version is not 1.
The features resolver is also able to refresh the bundles when an optional dependency is satisfied, rewiring the optional import. If you want to force Apache Karaf to reload the features repository URL and so update the features definition , you can use the -r option:. To register a features repository and so having new features available in Apache Karaf , you have to use the feature:repo-add command.
This argument accepts:. You can directly provide a features repository name to the feature:repo-add command. You can specify a target version with the version argument:. If you specify the -i option, the feature:repo-add command registers the features repository and installs all features described in this features repository:. If the features repository XML changes, you have to indicate to Apache Karaf to refresh the features repository to load the changes. Instead of refreshing all features repositories, you can specify the features repository to refresh, by providing the URL or the features repository name and optionally version :.
The feature:repo-remove command removes a features repository from the registered ones. If you use -u option, the feature:repo-remove command uninstalls all features described by the features repository:. The feature:list command lists all available features provided by the different registered features repositories :.
By default, the feature:list command displays all features, whatever their current state installed or not installed. It requires the feature argument. If only the name of the feature is provided not the version , the latest version available will be installed.
By default, the feature:install command is not verbose. If you want to have some details about actions performed by the feature:install command, you can use the -v option:. If a feature contains a bundle which is already installed, by default, Apache Karaf will refresh this bundle.
Sometime, this refresh can cause an issue with other running applications. If you want to disable the auto-refresh of installed bundles, you can use the -r option:. You can decide to not start the bundles installed by a feature using the -s or --no-auto-start option:. However, you can specify the -s option to the feature:install command. As soon as you install a feature started or not , all packages provided by the bundles defined in the feature will be available, and can be used for the wiring in other bundles.
You can also stop a feature: it means that all services provided by the feature will be stopped and removed from the service registry. However, the packages are still available for the wiring the bundles are in resolved state. The feature:uninstall command uninstalls a feature. As the feature:install command, the feature:uninstall command requires the feature argument. If only the name of the feature is provided not the version , the latest version available will be uninstalled.
The features resolver is involved during feature uninstallation: transitive features installed by the uninstalled feature can be uninstalled themselves if not used by other feature. You can "hot deploy" a features XML by dropping the file directly in the deploy folder. Features is a tabular data set of all features name and version provided by this features repository.
