I tried to create a basic virtual reality IDE based on Karaf.
I have 3 maven-projects:
VRServer who connect to a native-component for rendering.
VR Component Toolkit for VR-HMI-Widgets (Having a VRFrame who extends from VRComponent) as a Multi-Module-Maven-Project.
The VR IDE project read/write files and execute lowlevel commands.
I installed all of them into Karaf:

As the Logging points-out:
Caused by: java.lang.ClassNotFoundException: de.e_nexus.vr.tk.VRFrame not found by de.e-nexus.component [87]
What means Karaf is searching the VRFrame from the component submodule, which clearly does not exist.
That makes sense since all java packages are exported, the VRFrame's package is ambiguous. I followed what özkan pakdil said and renamed the java-packages to a unique name. Since that it works like a charm.
Thanks Özkan! Your answer includes some usefull hints and the source of my problem was the ambiguous package-name.
The main problem in the project is <extensions>true</extensions> in maven-bundle-plugin. You need to have it in your pom.xml. example code
<plugin>
<groupId>org.apache.felix</groupId>
<artifactId>maven-bundle-plugin</artifactId>
<version>5.1.1</version>
<extensions>true</extensions>
<configuration>
<instructions>
<Bundle-SymbolicName>${project.artifactId}</Bundle-SymbolicName>
<Bundle-Version>${project.version}</Bundle-Version>
<Bundle-Activator>${Bundle-Activator}</Bundle-Activator>
<Export-Package>
de.*;version=${project.version}
</Export-Package>
<Import-Package>
*
</Import-Package>
</instructions>
</configuration>
</plugin>
And packaging should be bundle like <packaging>bundle</packaging> for the OSGI bundles. You can see how package created from this command
mvn archetype:generate \
-DarchetypeGroupId=org.apache.karaf.archetypes \
-DarchetypeArtifactId=karaf-bundle-archetype \
-DarchetypeVersion=4.3.0 \
-DgroupId=io.github.ozkanpakdil \
-DartifactId=myfirstbundle \
-Dversion=1.0-SNAPSHOT \
-Dpackage=io.github.ozkanpakdil
https://karaf.apache.org/manual/latest/#_creating_bundles is explaining nicely. Other then that I highly suggest have namespaces without underscore. Instead of "e_nexus" have enexus and for <groupId>de.e-nexus</groupId> have <groupId>de.enexus</groupId>. Last but not least instead of <artifactId>vr.server</artifactId> have <artifactId>vrserver</artifactId>, I am suggesting these because OSGI is already complicated enviroenment, having simple and easy names will make easier to catch errors and maintain the code. Also it will prevent problems in case you move to another OS, you never know how these behaves between OSes.
There were some warnings related to same namespace is in different jars, I changed the code in "frame" and "component" modules accordingly. Below is the log from local, I can see that VR-Client log, I think it started working as expected.

I was trying karaf4.x with the DS(declarative service) in command bundles, but found it falied to get service via DS.

On starting apache karaf I'm getting the following error:

WARN | wrapper | 2017/01/30 14:42:52 | The value of property 'wrapper.java.additional.4', 'org.apache.karaf.main.Main' is not a valid argument to the jvm. Skipping.
The jar file it is looking for and the class within are fine (%KARAF_BASE%/lib/karaf-wrapper-main.jar)
Is fine. A colleague had a similar problem and it was JVM related but cannot remember what.
Does anyone know where I can even start with this because it should work. I have java 8 on my machine, but I have removed all references to it and my JAVA_HOME is pointing at this version 7, don't know if that makes a difference.
Note, the actual stack traces are something like

I am using Camel 2.17.3 and karaf 4.0.7 (also tried 4.0.1).
I have a Camel route that runs fine in Eclipse when a junit test starts it, but hangs when deployed to karaf. If I change the amqp: 'from' component to timer: the route runs fine in karaf.
My AMQP setup in the routebuilder is:
#Override
public void configure() throws Exception {
getContext().addComponent("amqp", AMQPComponent.amqpComponent(String.format("amqp://%s:%s?amqp.saslMechanisms=ANONYMOUS", AMQP_SERVICE_HOST, AMQP_SERVICE_PORT)));
Even this route will hang karaf, and run fine in Eclipse:
from("amqp:queue:myqueue").routeId("myRoute")
.log("temp")
In Karaf, when I say "hang", I observe these things:
If I try to exit karaf, it hangs - I need to kill the process.
If I try to stop the bundle, karaf hangs - I need to kill the process.
Neither camel:context-list nor camel:route-list return anything
I do not get a "route consuming from..." message in the log. This is all
the output from starting the bundle:

Any help would be hugely appreciated. Thanks!
The reason should be related to this issue in Camel JIRA: https://issues.apache.org/jira/browse/CAMEL-10278
The main problem is proton-j 0.10 is incompatible with qpid-jms-client version 0.8. We upgraded the dependency to proton-j 0.12.0 and the fix will be available in the Camel 2.17.4 release.
For the moment you can use Camel 2.17.4-SNAPSHOT or upgrade the dependency in the Camel-Amqp Karaf feature.
Below is the error from the log that i see after starting the service... can you help resolving this issue.

In case you use Aries JPA you should see two EntityManagerFactory services:
jpa-container picks up your bundle with the persistence.xml and creates an Entity manager factory
jpa-container-context picks up every EntityManagerFactory service and makes a new managed EntityManagerFactory service with the (org.apache.aries.jpa.proxy.factory=true) service property key-value pair
The second does not exist in your environment. There can be two causes:
aries-jpa-container-context is not in your OSGi environment or it is not in ACTIVE state
The original EntityManagerFactory service is not registered as some dependency is missing
You can check it if you open an OSGi console and check what services available. If there is no EntityManagerFactory service at all, the second is your problem.
Check if all of your bundles are active! If they are, check if you have all the services that jpa-container needs: TransactionManager, DataSource or DataSourceFactory and a javax.persistence.spi.PersistenceProvider service for Hibernate. If any of the services are missing aries-jpa-container will pick up your bundle but will never create the EntityManagerFactory.
I implemented an own jpa-container that works almost the same way as aries-jpa-container. If you replace the aries-jpa-container (only that one, the jpa-container-context should be left there) it will log more messages at INFO level for you what is missing. The container is available here. A sample application is available that uses hibernate is available at https://github.com/everit-org/osgi-hibernate. After running "mvn install" you will find itests/core/target/eosgi-itests-dist/equinox a subfolder where you can start the working application with on equinox server with bin/runconsole.sh.
The current aries jpa container jar 1.0.0 has a bug that makes it swallow exceptions on creating the EntityManager. A colleague of me opened the aries bug: https://issues.apache.org/jira/browse/ARIES-1160
I created a second patch that can be applied to the 1.0.0 sources to create a jar that correctly logs the exception. Check out the 1.0.0 tag of aries jpa container, apply the patch and build.
When you then run in karaf you should see the real source of the error.
