Question

While migrating from JBoss 4.3 to 5.1 the following issue occured:

The first Exception occurs during deploy time with no implementation of EJBLocalObject:

Caused by: java.lang.IllegalStateException: EJB 3.0 Core Specification Violation (4.6.9): The session beanÔÇÖs local interface interface com.company.project.BeanLocal must extend the javax.ejb.EJBLocalO
bject interface.

OK, then I implemented the interfaces, but JBoss isn’t satisfied and is now complaining: the bean must not implement EJBLocalObject!
Any Ideas?

EDIT: I should mention that the bean is a EJB3.0 with provides also an EJB 2.1 client view.

The declaration looks like this:

@TransactionManagement(TransactionManagementType.CONTAINER)
@TransactionAttribute(TransactionAttributeType.REQUIRED)
@Stateless
@RemoteHome(R2PRegistrationHome.class)
@RemoteHomeBinding(jndiBinding = JNDINames.BEAN_FOR_EJB_2_1_EJBHOME)
@LocalHome(R2PRegistrationLocalHome.class)
@LocalHomeBinding(jndiBinding = JNDINames.BEAN_FOR_EJB_2_1_LOCALHOME)
public class Bean implements BeanLocal, BeanRemote {
}

Answer 1

The Bean class should not implement component interfaces. Remove the implements clause from the Bean class, change the BeanLocal interface to extend EJBLocalObject, and change the BeanRemote interface to extend EJBObject.
