Please find my code below - to look up a EJB -

public

static TreeMap<String, String[]> getAuthentication(XmlHandlerRequestASM objReqHandAsm){



map = new TreeMap<String, String[]>();



try {



ctx = new InitialContext();

AuthenticationBean authEjb = (AuthenticationBean)

ctx.lookup("AuthenticationLocal");

XmlHandlerResponseASM objRespASM = authEjb.doLoginAdm(objReqHandAsm);



key = Constants.AdminConstants.authentication;



if(objRespASM.getStatus().get(Constants.Communication.STATUSCODE) != null ) {



values[0] = (String) objRespASM.getStatus().get(Constants.Communication.STATUSCODE);

}

else if(objRespASM.getStatus().get(Constants.Communication.ERRORCODE) != null ) {



values[0] = (String) objRespASM.getStatus().get(Constants.Communication.ERRORCODE);

}

else {



values[0] = "input";

}



map.put(key,values);

}

catch (NamingException e) {



//LoggerHelper.log(arg0, arg1, arg2, arg3)

e.printStackTrace();

}

catch (NullPointerException e) {



// TODO Auto-generated catch block

e.printStackTrace();

}

catch (TarangFrameworkException e) {



// TODO Auto-generated catch block

e.printStackTrace();

}



return map;

}



Below is the AuthenticationBean class ::



@Stateful

@Local

(AuthenticationLocal.class)

@LocalBinding

(jndiBinding="AuthenticationLocal")

@Remote

(Authentication.class)

@RemoteBinding

(jndiBinding="Authentication")

public



class AuthenticationBean implements AuthenticationLocal{



Appreciate any ideas to resolve my application issue.

Thanks in advance..
NK
