User development, A new message was posted in the thread "Migration from JBoss 4.2.3.GA to JBoss 5.0.0.GA": http://community.jboss.org/message/520093#520093 Author : Alexei Sadovnikov Profile : http://community.jboss.org/people/pualsa Message: -------------------------------------------------------------- I know, I'm one year late but I have the same problem. The JBoss AS 5.1.0.GA throws exceptions when I try to lookup EJBContext. As a workaround I'm suggesting to use SecurityAssociation from the jbosssx.jar: {code} import org.jboss.security.SecurityAssociation; ... String callerName = SecurityAssociation.getCallerPrincipal().getName(); {code} -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/520093#520093
