I'm trying to connect to Weblogic JMS from within Karaf. I've
wrapped wlthint3client.jar Weblogic from Weblogic in an OSGi bundle. I use
the following code:
Hashtable<String, String> env = new Hashtable<String, String>();
env.put(Context.PROVIDER_URL, "t3://127.0.0.1:7001");
env.put(Context.INITIAL_CONTEXT_FACTORY,
"weblogic.jndi.WLInitialContextFactory");
InitialContext ctx = new InitialContext(env);
This works perfectly outside OSGi but in Karaf I get:
Caused by: java.lang.ClassNotFoundException: Failed to load class

It looks like the the classloader being used is the frameworks classloader
(:1.6.0_32) which has not imported these packages. I have a feeling that it
is the service discovery mechanism that is failing. I know that Servicemix
has wrapped several bundles and made it possible for Java's service
discovery mechanism to work.
Am I doing this all wrong or should my code work? Also, if I want to
support service discovery the way ServiceMix bundles do - how do I do this?
Is there a good example bundle I can look at?
