Accessing User subject or User principal

2008-11-16 Thread Rob Mercer 
Hey,

 

Tomcat 6.0.14, Vista BE

 

I'm trying to implement a JAAS Realm solution, I'm unable to after
setting the subject/principal figure out how I'm supposed to
programmatically access either of these values after they've been set in
my LoginModule's commit() call?

 

I verify that my custom login modules' commit is called (see below). My
question is how do I access the principal that's stored here?

 

  public boolean commit() throws LoginException {

if (succeeded) {

  if (subject.isReadOnly()){

throw new LoginException(Subject is
readonly!);

  }

  // add a Principal (authenticated identity)

  // to the Subject

 

  userPrincipal = new UserPrincipal(username);

 

  assignPrincipal(userPrincipal);

  

  assignPrincipal(new
UserPrincipal(AccountRole.PATIENT.getCode()));

  

  // in any case, clean out state

  username = null;

  for (int i = 0; i  password.length; i++)

password[i] = ' ';

  password = null;

 

  commitSucceeded = true;

  

}

return true;

  }

 

 

Then, somewhere else in the code (say on a page), I try to figure out
who's calling the code? And the getSubject() line returns null.

try {

  LoginContext lc2 = new LoginContext(Jaas);

  lc2.getSubject();

} catch(LoginException le ){

  le.printStackTrace();

}

You're supposed to access these values by calling getUserPrincipal() on
the HttpServletRequest object.

First off, thanks for the quick response!

 I've tried to make that call but keep getting null values back for
both the getUerPrincipal and getRemoteUser on the HttpServletRequest...
do I need to wait until the next request to make these calls or is it ok
to check them immediately after the commit is called?

It should work immediately. You might want to try a build from trunk as
there have been a number of JAAS fixes that will be in 6.0.19.
