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.
Its shows like below image for long time.
I deleted *.dmp file which is located on
C:\Program Files\Research In Motion\BlackBerry Smartphone Simulators 7.0.0\7.0.0.261 (9900)
But problem hasn’t been resolved.

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.
