Java Mission Control jmc WebLogic plugin

funnily, the plugin installs, but whenever I run it, it says "event type BLA is not enabled in this recording" and I can't figure out how to enable the event recording...

this video is about the JRockit version:

To install: run jmc.exe, Help, Install new Software


If you see this when activating Commercial Features via JMC:
