Hi,
I've edited eclipse.ini as per Jeff's email below, and that seems to
have fixed the problem.
I wasn't able to get JConsole working.
I added this to eclipse.ini:
-Dcom.sun.management.jmxremote
I also added it to the Tomcat VM args, but when I startup JConsole via
the command line, it doesn't display any running Java processes.
Any ideas Brian?
PS. I'm trying to monitor my webapp running on Tomcat via Eclipse.
From the JConsole examples I've seen, it seems to work fine for java
applications started via command line.
Furthermore, I am now getting another exception on context reload:

Subject: [CTJUG Forum] Re: java.lang.OutOfMemoryError: PermGen space
Hi
Yep, far too often.... I run eclipse 3.2 with JBoss 4.0.4
To set the Perm Mem, use the following params; Ilanded up setting the
eclipse.ini and the JBoss configuration within eclipse.
-XX:PermSize=128M
-XX:MaxPermSize=256M
Hope this helps....
Cheers
