BMP Bean deployed but ClassCastException

[jelid]

Hi,
I realize an entity-bean (Bean managed persistence) and deploy it correctly but when i try to get the Home interface, I got a ClassCastException.

Has anyone an Idea of the problem?
Here under i report pieces of the code I hope are enough to resolve the problem!

############client code ##################
Client code that generate the exception:
Context jndiContext = getInitialContext();

Object ref = jndiContext.lookup("SavingsAccountHomeRemote");

SavingsAccountHomeRemote home = (SavingsAccountHomeRemote)
(PortableRemoteObject.narrow(ref,SavingsAccountHomeRemote.class));
#############ejb-jar.xml (essential)##########

Many thanks.

I was almost desperate.

The link is very useful!!!

My situation was the following:
Servlet client of the EJB and the EJB on the same Server (ClassLoading problem).
I resolve the problem setting the Class-Path property in the MANIFEST of the Client including the original jar file of the EJB.

You save me a lot of time.
