I\'ve installed blackberry os 7 simulator (9900,9930,9850).
When I open the simulator, the blackberry loading screen is displayed. But Not loading completley.
<Install BlackBerry Java Plug-in 1.3.0 and it will work.. I am currently working on it. I haven't checked with the older versions of eclipse plugins.
In eclipse, Go to Blackberry menu > Select Clean Simulator option and then run your simulator.. It will delete all dmp files,debug files and set to default setup.
I got the same problem.. but now it works fine for me... This answer may be helpful to you.
