Hi,

I am trying to using a stateful session bean to update an entity using extended persistence context. But I get the following error when trying to access the stateful bean from a standalone class:


Caused by: java.lang.IllegalStateException: Extended Persistence Contexts can only be invoked from within the context of the stateful session bean that declares the Extended Persistence Context.
at weblogic.deployment.ExtendedEntityManagerProxyImpl.getPersistenceContext(ExtendedEntityManagerProxyImpl.java:61)
at weblogic.deployment.BasePersistenceContextProxyImpl.invoke(BasePersistenceContextProxyImpl.java:88)
at weblogic.deployment.BasePersistenceContextProxyImpl.invoke(BasePersistenceContextProxyImpl.java:80)

at java.lang.StringBuilder.append(StringBuilder.java:115)
at containerNamagedEM.DeptServiceImpl.init(DeptServiceImpl.java:26)
... 40 more



Below is my stateful bean class



The standalone test class to access the session bean:



I am using weblogic 10 and below is my persistence.xml:



Can someone help me to solve this issue?

Thanks in advance,
Amitava
