Try in the web forums.
the version of jboss
whether you use jbossweb(jetty) or tomcat
whether you have clustering enabled.
I'm assuming this is a web session not a session bean.
Sorry i knew that.
I've tried it on jboss 3.0.2 and 3.0.3 with jetty. Not ont the tomcat environment.
Maybe i'm doing something wrong but i would expect an exception and not a hanging machine.
I wouldn't expect it hang either.
You could try dumping the threads to see if there
is a deadlock.
Probably control-break, check your jvm docs.
