Hi,
I have a problem accessing JNDI resources from within an OSGI bundle, hosted in
WebSphere Application Server (WAS) using a servlet bridge.
It is failing on creating the JNDI initial context. My code is:
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.ibm.websphere.naming.WsnInitialContextFactory");
InitialContext ctx = new InitialContext(env);
This fails with:
javax.naming.NoInitialContextException: Failed to create InitialContext using factory specified in hashtable {java.naming.provider.url=corbaloc:rir:/NameServiceServerRoot, java.naming.factory.initial=com.ibm.websphere.naming.WsnInitialContextFactory, java.naming.factory.url.pkgs=com.ibm.ws.naming:com.ibm.ws.runtime:com.ibm.iscportal.jndi} [Root exception is java.lang.NullPointerException]
When I run the same code directly within a WAR module (not using OSGI), it is successful. I assume therefore the problem is something about accessing JNDI from within OSGI.
I have seen some references to Class Loader problems when accessing JNDI from within OSGI ... not sure if this is my problem, since the above exception does not explicitly relate to class loading, but maybe it is. Anyhow, if this is the problem, I am not sure how to fix it!
Is it in fact possible to access JNDI and JDBC entries set up within WAS, from within my OSGI module?
My application is an Eclipse RAP (Rich Ajax Plugin), packaged into a WAR file using the Eclipse WAR Product Tooling described at:

This works successfully so far, apart from the JNDI access.
Many thanks
David
