Problem in Websphere

Hi Everyone,
The Exception i got is as below:
java.lang.ClassCastException: Unable to load class: org.omg.stub.com.newgen.omni.jts.txn._NGOClientS
erviceHandlerHome_Stub
My code is as follows:
Object home = ctx.lookup("com.newgen.omni.jts.txn.NGOClientServiceHandlerHome");
NGOClientServiceHandlerHome clientServiceHandlerHome = (NGOClientServiceHandlerHome) PortableRemoteObject.narrow(home, NGOClientServiceHandlerHome.class);
NGOClientServiceHandler clientServiceHandler = (NGOClientServiceHandler) PortableRemoteObject.narrow(clientServiceHandlerHome.create(),NGOClientServiceHandler.class);
Our actual package structure is com.newgen.omni.jts.txn. But we dont understand, why our package structure is
prefixed with omg.org.stub while trying to type cast.We have searched in many related web-sites where this problem
is posted but no one has posted the solution for this problem.
Help is needed urgently.
Thanks
Sumona

Do you have the _Stub and _Tie classes of your EJB packaged within the Jar file.
(did you generate the RMI code)

Thanks for the reply Bill.
I am using Websphere 4.0 and by AAT i created deployable jar.RMIC was invoked by AAT.I have the _Stub and _Tie in my jar file but in com.newgen.omni.jts.txn package.
But while casting the object container is searching in org.omb.stub.com.newgen.omni.jts.txn package.

No idea Sumona.
Maybe you should post here your exact configuration (was version + patch)to obtain some help from the ranchers.
Don't forget to let use know which visibility you are using (module, server, application, J2EE etc..)
Maybe you could also activate a classloader trace device to have further information about your problem.
For instance :
com.ibm.ws.classloader.*=all=enabled
or
com.ibm.ws.classloader.Compoundclassloader=debug=enabled
may help
By the way, don't forget to take a look at the JavaRanch Naming Policy before sheriffs catch you and lock you out
