    Migration from JBoss 4.2.3.GA to JBoss 5.0.0.GA

    mailman2009 Feb 24, 2009 3:11 AM

      Hi,
      in JBoss 4 this code will works fine:

      @Stateless
public class GetUserName implements GetUserNameLocal {

 public GetUserName() {
 }

 @Override
 public String getUserName() throws NamingException {
 InitialContext ic = new InitialContext();
 EJBContext sctxLookup = (EJBContext) ic.lookup("java:comp/EJBContext");
 Principal principal = sctxLookup.getCallerPrincipal();
 String userName = principal.getName();

 return userName;
 }
}


      On JBoss 5 i get the following exception:

          I have found one mistake.
          I have used the constructor from GetUserName to use the class. I have changed this and now i use the lookup:

           InitialContext ic = new InitialContext();
 GetUserNameLocal getUsername = (GetUserNameLocal) ic.lookup("GetUserName/local");
 userName = getUsername.getUserName();

          Now I get no exception.

          But the the username is not the user that is logged on the session. I get "anonymous".

          Why?

            Hi, in the case of an EJB it is better to use injection of a SessionContext instead of JNDI lookup:

            {code}@Resource
            private SessionContext ctx;
            {code}

             

            I have the same problem in my EntityListener POJO class. The JBoss AS 5.1.0.GA throws exceptions when I try to lookup EJBContext, but it worked in JBoss AS 4.x. 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}
