Error
weblogic.application.naming.ReferenceResolutionException: [J2EE:160199]Error resolving ejb-ref "<PACKAGE_NAME>.<SERVLET_NAME>" from module "<WARFILE_NAME>" of application "<APPLICATION_NAME>". The ejb-ref does not have an ejb-link and the JNDI name of the target bean has not been specified. Attempts to automatically link the ejb-ref to its target bean failed because multiple EJBs in the application were found to implement the "<PACKAGE_NAME>.<CLASS_NAME>" interface, including <JARFILE_NAME>/<CLASS_NAME>, <WARFILE_NAME>/<CLASS_NAME>. Specify a qualified ejb-link for this ejb-ref to indicate which EJB is the target of this ejb-ref.
