Please post the source code for your EJBs, and for any EJB configuration files. Also post the output from running listAll on the JNDIView (see http://www.redhat.com/docs/manuals/jboss/jboss-eap-4.2/doc/Server_Configu...) Also post the client code used to access the EJBs (I assume this would be the body of the callZoneMethod() method) Make sure to enclose the source code and XML text within code tags (select the text and click the Code button under the editor window).
