How to access "Alternative Realm" or "Custom Realm" from components like Servlet ?

Question

Hello,
Says if I have alternative realm or my custom realm which implement
"ManageableRealm" interface. How can I access the realm from other
component, like Servlet or EJB in same WLS ? I tried using code like this
BasicRealm realm =
Realm.getRealm("XmlRealm","weblogic","myclass.DebugRealm");
if (realm != null) {
Class realmClass = realm.getClass();
out.println("Realm is " + realmClass.getName());
Which "myclass.DebugRealm" is classname of my own realm. This realm works
fine when using for authentication and authorization. But when I run this
code on servlet, it seems that it doesn't return the realm it created when
starting WLS, I mean the one that served authentication and authorization.
But it create a new instance of this class (I knew it 'cos I put debug
message in its constructor). So how can I get reference to the realm
instance which is created when starting WLS ?
Thank you in an advance,
Siros

Hello again,
Sorry to say that now I've got the way. I post here again for someone who
may face that same problem.
So strange that, I just changed the realm name in below code to "custom" and
then it works !! My realm is extended from "AbstractListableRealm" class and
I think I named my realm as "XmlRealm" in it constructor by call
super("XmlRealm");
But seems like its "getName()" method always return "custom", so in servlet
code, it' rather be.
BasicRealm realm = Realm.getRealm("custom");
if (realm != null) {
Class realmClass = realm.getClass();
out.println("Realm is " + realmClass.getName());
This works fine and no instance of realm is created. Anyway I saw that
constructor of "AbstractListableRealm" take String argument for "name" of
the realm. So why it's always "custom" ???
Comments are welcome,
