Create JAAS Subject

Hello Everybody,
I would like to create a JAAS Subject through my java web application. Can some one please provide a sample code or a link where I could read more regd the steps required for the creation of a JAAS Subject in a Web Application . I will be deploying the application in a Webshere App Server. Any help would be greatly appreciated.

Thanks.
Smith.

Welcome to JavaRanch.

Normally you'd get the Subject from the LoginContext after a successful authentication; see http://java.sun.com/developer/JDCTechTips/2001/tt0727.html for an example. You'll need to configure WebSphere accordingly (meaning, it needs to be told where JAAS can find user information, whether in a DB, or LDAP, or elsewhere).

Hi Ulf,
I appreciate the response provided and also for the link. You are right, we need to go against the DB or LDAP. Basically I have created a custom Login Module and inside the login() method I was going against a DB to get the user Authenticated and finallay I was able to get a JAAS Subject created. But now I need to pass this JAAS Subject from one application to another application residing on a different App Server ? How can this be done. Any ideas ?

-Thanks.

That sounds like a single sigh-on (SSO) solution is called for. There was some discussion on this in http://www.coderanch.com/t/134584/Security/Understanding-JAAS-Web-app-SSO.
