This is what I did:
1. Clicked the “Monitoring Dashboard” from Weblogic console
2. On the left pane, under “Build-in views”, clicked “JMS Runtime”
3. Click the green start buttion
On the right pane, there are two sections, however both are blank - no data/graphs displayed.
It should work. Is this a single server or a clustered environment?
What happens if you do the same, but selecting "JVM Runtime Heap", instead?
Does it work?
Which browser/version are you using? I'm asking, because Internet Explorer 6 for example would be very slow, and hang some times.
