Examples of com.sun.ejb.containers.EJBObjectImpl

com.sun.ejb.containers.EJBObjectImpl
EJBObjectImpl implements EJBObject methods for EJBs. It is extended by the generated concrete type-specific EJBObject implementation (e.g. Hello_EJBObject). Instances of this class are NEVER given to beans or clients. Beans and clients get only stubs (instances of the stub class generated by rmic).
