Debug Blackberry App in Simulator using Eclipse Plugin

I have just started the Hello World App using Blackberry Eclipse Plugin.

I have tried one or two configuration for debug my HelloWorld Blackberry App, but unfortunately I could not..

Can anyone let me know that how can I debug any Blackberry App in simulator using Eclipse Plugin ?

Thanks in advance...

EDIT : When I am trying to do so using Debug Configuration开发者_StackOverflow中文版 option in Eclipse I am getting following error :

"Failed to connect to remote VM. Connection timed out. org.eclipse.jdi.TimeoutException"

with following stacktrace :
