JNDI lookup from Portal Application Module

Question

Dear Experts,
I have a problem with looking up a Deployable Web Service Proxy from within a Portal Application Module.
I use NWDI and created both the Deployable WS Proxy DC and the Portal App DC.
I added the generated Proxy to the Proxy DC's public part and added it as used DC to the Portal Module DC.
When I perform the JNDI lookup, no exception is thrown but the Code is not executed any further...
Here is the source:
Category.APPLICATIONS.infoT( loc, "lookup JNDI...", new Object[] { this });
Object o = ctx.lookup(JNDI_NAME);
Category.APPLICATIONS.infoT( loc, o.getClass().getName(), new Object[] { this });
service = (OrchestrationService)o;
Category.APPLICATIONS.infoT(loc, "success!", new Object[] { this });
The log shows the name of the class (OrchestrationServiceImpl) but not the success! part.
As I said: No exceptions are thrown...
Any help is appreciated!

Solved the problem!
It's allways the same:
As soon as you ask the question the answer comes to you by itself...
I needed to add a reference to the using DC. I already did that before but not correctly:
If you want to add a reference to a j2ee application you need to read this document:
[Calling J2EE Applications from Portal Applications|http://help.sap.com/erp2005_ehp_03/helpdata/EN/42/9ddf20bb211d72e10000000a1553f6/frameset.htm]
It says the reference has to look like this:
<property name="SharingReference" value="SAPJ2EE::sap.com/Hello"/>
I hope it helps someone.
