[jboss-user] [EJB/JBoss] - Extending Principal and using getCallerPrincipal()

[harryworld]

Hi,

I would like to ask a question about the stated topic.

My case is like that:
The SimplePrincipal originally shipped with JBoss is not enough to me, it contains only name, but I would like to add some more variables. Thus, I made my own MyPrincipal implementing java.security.Principal.

anonymous wrote : 
  | public class MyPrincipal implements Principal, Serializable {
  | ...
  | }
  | 

Moreover, I have made a new MyLoginModule extending DatabaseServerLoginModule, this class overrides the createIdentity() method so that the Principal instance created must be of the class MyPrincipal.

anonymous wrote : 
  | public class MyLoginModule extends DatabaseServerLoginModule {
  | ...
  |   protected Principal createIdentity(String username) throws Exception {
  |     MyPrincipal p = null;
  |     if (principalClassName == null)
  |       p = new MyPrincipal(username);
  |     } else
  |       p = (MyPrincipal) super.createIdentity(username);
  |     return p;
  |   }
  | }
  | 

These classes run successfully, and I did check the Principal created after the login() method is an instance of MyPrincipal.

Now, is the problem. Am I able to get this Principal in a Session Bean?

Before I made the new Principal and LoginModule, I can get the Principal instance through its interface using the sessionContext.getCallerPrincipal() method. I checked the instance I got and it is of the default class type - SimplePrincipal.

However, after I used the the new one - MyPrincipal, the result shows me the sessionContext.getCallerPrincipal() method also returns an instance of SimplePrincipal. Is this method points to the same Principal instance as the one I got in login()?

If not, is there any method for me to get the instance created in login()?

Thanks for your kindness and sincere help.
