Recently, I have been working on Apache Karaf project.
The first one is a CXF REST service example and the second one is an Apache Karaf Maven example to run and deploy a Karaf container.
What I would like to do is to combine these two. The idea is to download a couple of JAR files from a repository and then package them into a Karaf.
Building Karaf Assembly manually then deploying the created JAR files in my deploy folder under Karaf is not a good idea if the task is reccurent each day. I would very much like to automate this if possible?
To achieve automatic deploy of Java project in Karaf, follow these steps:
Create a feature project: It is a Maven project and its goal is to create a descriptor of JAR (bundles) to be deployed under Karaf. The packaging of this Maven project is feature.
For your project of Karaf Assembly, add your feature as dependency and add it as boot feature so it can be installed when Karaf is up.
Look at this project https://github.com/benson-basis/karaf-feature-version-tc.
It has all the necessary configuration to automate Karaf building and deploy.

I would like to use maven to deploy a complete karaf server including my own features. But so far I am unable to find a way to add the karaf server itself as a dependency. This would save a lot of manual steps, esp. for the other developers which would not have to setup karaf manually.
This would have the added benefit that I do not have to check in the karaf server into the repository in order to have all required parts available from the repository.
Question: is there a way to configure a project using karaf which will setup the karaf server and all required dependencies without manually downloading the files from the karaf website?
This can be done using the karaf-maven-plugin. There is even an example which does this shipped with karaf: examples/karaf-maven-example.
Here is what the examples do
karaf-maven-example-run uses the karaf-maven-plugin:run goal to download and start a Karaf instance.
karaf-maven-example-run-bundle uses the karaf-maven-plugin:run goal to download, start a Karaf instance and deploy the project bundle in this running instance.
karaf-maven-example-deploy uses the karaf-maven-plugin:deploy goal to deploy the module artifact into a Karaf instance (remote for example).
karaf-maven-example-client uses the karaf-maven-plugin:client goal to execute a shell command on a running Karaf instance.
karaf-maven-example-kar packages a features repository as a kar file, ready to be deployed.
karaf-maven-example-assembly uses the karaf-maven-plugin to create a Karaf distribution.

I have an osgi bundle which was deployed in apache karaf using the feature.xml and service injection is done using blueprint.xml. How to deploy the same bundle in Weblogic OSGI container.
https://docs.oracle.com/middleware/1212/wls/WLPRG/osgi.htm#WLPRG764
I followed the steps mentioned in the above link. Copied the OSGI jar in the WL_HOME/server/osgi-lib location and restarted the server, but was not able to start it. Am i missing some thing?
Note:- I was able to deploy a simple OSGI jar without any dependencies by copying the jar in the osgi-lib folder.
You need to install the Aries blueprint bundles.
With Karaf 3 I can deploy wab project and war project.
I have made a no OSGi web project . I want to deploy that on Karaf 3. How to do it ?
Using netbeans , I have made a war file from my web project and I have install on Karaf 3 the .war project using that : bundle:install -s file:/path/myproject.war
I have no error for the install.
But I can't see that working when I go to http://localhost:8181/myproject .
Then Why that don't work? What is the problem ?
Thank you for your advice and help,
You might need to install the war feature first
feature:install war
Install the war feature first, with feature:install war as Christian already mentioned.
Though for a no-osgi war you'll need to install it with the webbundle prefix.
bundle:install webbundle:file:/path/myproject.war?WebContext-Path=myproject
Pax Web will create a OSGi war from it on the fly and this will be installed.
I am working on to reach a solution to deploy a web application as a bundle to Virgo 3.0.1.RELEASE. My scenario is:
I use Maven Bundle Plugin to generate the manifest.
I exclude all the JAR dependencies using Maven WAR plugin.
I need to command Virgo to host the plain Maven JAR artifacts in the local repository. As an instance Apache Karaf along with PAX can provide plain JAR files as OSGi bundles.
So,
Any ideas on how to configure Virgo for to host Maven repository plain JARs?
Generally, in your experience, what is the best solution to use a ready Maven repository and host it as an OBR?
Thanks in advance.
The best solution I've found so far is actually using Wrap Deployer on Apache Karaf.
Basically stick with Karaf, since it provides all you need :)
With Karaf and the features you don't really need a OBR, since the features service does a pretty good job of resolving already deployed bundles and won't install those again. You need to add the OBR flag to your features file though.
I am looking for a way to reach my vision. What is the best way to go?
Here is my vision:
I would like to build a captain casa app via maven (as a war file).
Then i would like to create a osgi bundle from the builded war via maven.
Next i would like build a artifact which could be downloaded and started via java webstart (jnlp).
The jnlp file should be download the osgi environment with web container support (maybe jetty osgi service), next download osgi bundled war. Then the osgi container and the jetty service should be started and my war should be deployed. Finally the app is running local in a osgi environment.
There are many questions to be answered:
How can i build a captain casa app via maven to a war?
Which maven plugin should be used to build the osgi bundle (pax, maven-bundle-plugin, tycho, ...) What are the differnce?
How to build a jnlp artifact via maven which can deployed on a site?
How must be modified the osgi bundle to support java webstart?
Known informations:
Blog entry to prepare osgi bundle for java webstart.
many pages to maven plugins, such as pax, maven-bundle-plugin, tycho, bnd, ...
It might be worth asking this as 3 separate questions, but when building Web application Bundles I use the maven-bundle-plugin version 2.2.0 (currently unreleased, so you'll need to depend on a snapshot).
Then I use the following file structure:
src/main/java - any .java files
src/main/resources - any non .java files that should be on the classpath
src/main/webapp - static content, images, html files jsps and so on
Then inside the pom once you have configured the normal data for the maven-bundle-plugin you specify the following:
<_wab>src/main/webapp</_wab>
this will cause the static content to be pulled into the bundle and the bundle to be structured with the classes and resources in the WEB-INF/classes directory.
