Linkage Error Looking up EJB from BPEL (11g)

Question

I am using 11g TP3.
I have a BPEL process that is using WSIF to call a plain java class. Then from this class I am attempting to lookup an EJB in another application (but on the same server).
My code looks like this...
env.put( Context.INITIAL_CONTEXT_FACTORY, "oracle.j2ee.rmi.RMIInitialContextFactory" );
env.put( Context.SECURITY_PRINCIPAL, "fmwadmin" );
env.put( Context.SECURITY_CREDENTIALS, "welcome" );
env.put(Context.PROVIDER_URL, "ormi://localhost:23891/DisEM");
javax.naming.InitialContext ctx =
new javax.naming.InitialContext(env);
Object obj = ctx.lookup("DisConfigManager");
I get a Linkage error on the lookup stating it "violates loader constraints" on class com/evermind/server/rmi/RMIClientConnection
Below is the full error text. Any help would be appreciated. Thanks.

Answer 1

I was mistaken in this posting. I was able to access the EJB from the startup class so there must be something else that I am doing to cause this problem. I'd still like to know why I get those invalid guid errors though.
By the way, please forgive me for using the gender-specific gentlemen in my posting. That was accidental.
