com.ibm.websphere.naming.CannotInstantiateObjectException

[roberto...@datatex.it]

Hi

I have an ear application composed by a war and ejb jars.

I recieve this exception trying to access a local ejb session.

{code}
raccia di stack dell'eccezione: com.ibm.websphere.naming.CannotInstantiateObjectException: A NameNotFoundException occurred on an indirect lookup on the name java:comp/env/ejb/ABSUserDefSession. The name java:comp/env/ejb/ABSUserDefSession maps to a JNDI name in deployment descriptor bindings for the application performing the JNDI lookup. Make sure that the JNDI name mapping in the deployment descriptor binding is correct. If the JNDI name mapping is correct, make sure the target resource can be resolved with the specified name relative to the default initial context.

EJB JNDI names

ejb/ABSUserDef is an entity ejb reference used by the Session ejb/ABSUserDefSession.

I try to undeploy and regenerate all and now it is working fine.

So I can consider it closed.

Ty anyway to all
