I tried to write a simple appn using jpa


SessionBean :


But getting error at the time of deployment on weblogic 10.3.3 server:
Unable to deploy EJB: BookCatalogBean from book.jar:

No persistence unit named 'EntityBean' is available in scope book.jar. Available persistence units: []

at weblogic.ejb.container.deployer.EJBModule.prepare(
at weblogic.application.internal.flow.ModuleListenerInvoker.prepare(
at weblogic.application.internal.flow.DeploymentCallbackFlow$
at weblogic.application.utils.StateMachineDriver.nextState(
at weblogic.application.internal.flow.DeploymentCallbackFlow.prepare(
Truncated. see log file for complete stacktrace

Caused By: java.lang.IllegalArgumentException: No persistence unit named 'EntityBean' is available in scope book.jar. Available persistence units: []

at weblogic.deployment.BasePersistenceContextProxyImpl.<init>(
at weblogic.deployment.TransactionalEntityManagerProxyImpl.<init>(
at weblogic.deployment.BaseEnvironmentBuilder.createPersistenceContextProxy(
at weblogic.deployment.BaseEnvironmentBuilder.addPersistenceContextRefs(

try to be more clear, i'm in lack of ideas in this problem, even it sounds like a classic :I have spend hours trying to play around with this but have got nowhere.

and WebClient.jsp with bci = (BookCatalogInterface) ic.lookup("entity/library/BookCatalogInterface");
But getting error
Error:Unable to resolve 'entity.library.BookCatalogInterface'. Resolved 'entity.library'
I check jndi tree on console which specify Binding Name:
