I have written an application with a secure EJB3 module and a swing GUI app
client that is run via java webstart. Everything works great, with
authentication for test users allowing me access to the secure EJB. I am using
netbeans 6 and glassfish v2 with java 1.5

The problem is that I want to customize the GUI login dialog that pops up. The
default GUI login dialog that glassfish provides is not sufficient. I have
implemented a callback function and when I run it I get and exception (all can
be seen below): "No LoginModules configured".

I want to keep using the LoginModules in glassfish with the jdbcrealm and don't
want to write one myself, so I don't know how to proceed. Where do I tell my
code to just use the default login module that glassfish was using before?

I have the following callback code:

After I see the login window from the above code I get the following exception:
