Getting a list of roles from Identity

[lholmquist]

I have a custom authentication method that gets the roles for a specific user from a db.  the roles are added using the identity.addRole('role') method.   is there a way to then list these roles that i have added.  i know i can use the hasRole method to restrict things.  but it would be nice also show the roles for that user.

Yes you can gather the roles of a user like this:

#{identityManager.getImpliedRoles(USERNAME)}

Thanks for the quick reply.   what version of seam is this in.  I am using jboss developer studio and chose the Seam 2.0 project wizard.  I was unable to find the IdentityManager class. I would also like to point out that i am a Seam noob

thanks

If i use the 2.1 project wizard, its there.

Another Question.    I'm new to seam and have been using the Seam Framework second edition book.   I see that using the IdentityManager u can do all the CRUD operations with it.  I don't normally mapped my pojo's to a db.  i like to write the querys myself.  How do u extend the Identity Manager functionallity to write those custom query's.

i'm sorry if this is not a seam question

if you just wan't to know the roles hold in the identity object you can try this:

public List<String> getIdentityRoles(Identity identity) {
      List<String> roles = new ArrayList<String>();
      Subject subject = identity.getSubject();

      for (Group sg : subject.getPrincipals(Group.class)) {
         if (Identity.ROLES_GROUP.equals(sg.getName())) {
            Enumeration<Principal> e = (Enumeration<Principal>) sg.members();
            while (e.hasMoreElements()) {
               Principal member = (Principal) e.nextElement();
               roles.add(member.getName());
            }
         }
      }
      return roles;
   }
