I have installed Glassfish v3.0.1 (build 22) on a Windows 2008 Server (system is otherwise pretty bare - glassfish is it's primary purpose).
I experience the same error in both IE8 and Firefox 3.6.8
When I attempt to edit or ping a connection pool, I get this error:
[b]java.lang.IllegalStateException: PWC3991: getOutputStream() has already been called for this response
[/b]
Not sure if its helpful info, but I had my domain running well on another machine on GF2. I installed GF3 on the previous machine, and let GF3 upgrade the domain automatically. Then I copied the upgraded domain.xml to the new server. My web application seems to be working fine - and the connection pools are working. But when I try to access them from the admin console I experience errors.
I am attaching the full server log which contains full stack traces at bottom.
Thanks in advance!
