Cannot create CMP bean, Error: "Werent current caller"

Question

Hi,
I generated a CMP entity ejbean with JDeveloper and deployed it. I can use that bean with a client and retrieve a specific instance using the home interface's findByPrimaryKey() method.
But I can not create a new bean using the home interface's create( long newPrimKey) method. The following error occures only if the specified newPrimKey is not occupied yet. If I use an occupied key, I get an expectable "javax.ejb.DuplicateKeyException"...
java.lang.InternalError: Werent current caller, server stacktrace (to disable this message, use -Dejb.assert=false at startup): java.lang.Throwable: Werent current caller

Any idea?? I'm really stuck with this!
Thank you.

Chris,
The problem is that both clients and EJBs are in the same server and you are using RMIInitialContextFactory. You have to use default context and package this client in the same EAR. Please look at http://otn.oracle.com/sample_code/tech/java/oc4j/htdocs/oc4jsamplecode/oc4j-demo-ejb.html#CMP for samples. Also some EJB/client sample programs are packaged with Oc4J disand you can find at $IAS_HOME/j2ee/home/demo/cmp distribution ctory.
However the client program should work fine if your client and EJBs are running on different Oc4J containers.

Hi Debu,
the client is a java application. Here is the code:
[...in main method...]
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.evermind.server.rmi.RMIInitialContextFactory");
env.put(Context.SECURITY_PRINCIPAL, "admin");
env.put(Context.SECURITY_CREDENTIALS, "admin");
env.put(Context.PROVIDER_URL, "ormi://CHRISTIANE/statful");
Context ctx = new InitialContext(env);
PersonHome personHome = (PersonHome)ctx.lookup("Person");
Person person;
person = personHome.create( 14261026 );
