java.lang.ClassNotFoundException on virgo [message #1712144]

After a few weeks of fruitless experimenting, I have come to the conclusion that I need help. This is the situation:

1: I run a virgo 3.6.4 kernel with a Jetty server
2: One of the bundles I have built uses twitter4j.jar, which is packed as a library in the bundle
3: When I run the bundle on a local target (RAP application) everything works fine.

Then I put the bundle on Virgo, and it throws the exception:

Caused by: java.lang.ClassNotFoundException: javax.crypto.Mac
(it starts up without problems, so the the exception is thrown when the code is called)

The Virgo kernel is configured with a standard java6 profile, which contains the required javax.crypto packages, so I fail to see why the packages are not recognised. I jave used various JRE/JDK versions, but all seem to throw the same exception.

The only thing that I can come up with is that the jetty server somehow does not see the javax.to code. I run the jetty server as a plan in its own repository and plan.

Any help as to where I need to look in order to fix this problem would be greatly appreciated!
Thanks

Hi Kees

You could add "javax.crypto" and "javax.crypto.*" to the "org.osgi.framework.bootdelegation" property in the "$SERVER_HOME/configuration/java6-server.profile" as we did on our side using Virgo Server for Apache Tomcat.
Or you can try to add it to "packageImports" in the "$SERVER_HOME/configuration/org.eclipse.virgo.kernel.userregion.properties". I can't remeber if we tried that but reading the documentation [1] this should be sufficient.
Let me know if you could resolve the issue.

Hi Daniel,

That solved it! java6-server.profile already has the packageImports set correctly, but not the bootdelegation. I added this and everything works fine now!

Thanks a lot!

Kees
