Is there anything interesting in the glassfish server log?
A thread dump on such a hung system should be the first thing you try.
I assume you're on windows, so "jstack" would probably the easiest way to get the thread dump.
Also what are the exact versions for GlassFish and the JVM?
Ideally the <java-config> section of your domain.xml would also be useful.
