I am trying to connect to a j2EE security enabled system using Programmatic login using the userId and Password but the subject object returned from lc.getSubject() is just Subject: . it is not even null though. My login is successful, but for subject object it is returning Subject: and when i go to next line i.e. WSSubject.setRunAsSubject() it is throwing me a null pointer exception.

Why is this happening. I am using JDK1.3 and is it because the JAAS is not compatible with JDK1.3 version. If it is so, how should i be able to establish a connection to j2EE secured application.

Any help is appreciated . Thanks in advance!

LoginContext lc = new LoginContext("WSLogin", new WSCallbackHandlerImpl(username, "realm", password));
lc.login();
log.info("Login done successfully " );
log.info("about to get subject");
Subject sub = lc.getSubject();
System.out.println("subject is:sub" );
WSSubject.setRunAsSubject(sub);

Here is the message is am receiving when i try to establish a connection:

[7/6/09 12:32:22:334 EDT] 0000002e SystemOut O Login done successfully
[7/6/09 12:32:22:334 EDT] 0000002e SystemOut O about to get subject

Assuming that you are testing in RAD and that you are connecting to an EJB instance :
Is you application server enabled for global security ?

If your app server is not enabled with Global security , you see null subject. So either you have to enable Global Security on local env or you should be using WebService instance of the service(if available)..

It has to be set from Server's adminstrative console after you configure your server.
Also, This link will be useful to know basics of j2ee Security ..

If you can give the steps to enable the Global security then it would be great help.
