How can I fix these problems with a BlackBerry PhoneGap project and the simulator?

Based on the instructions here, I started a PhoneGap project in Eclipse that targets BlackBerry. However, I'm running into two problems with this project:

1. If the simulator is not open, it will open but the app开发者_如何学Golication will not be installed properly.

2. If the simulator is already open, a message will appear with the text: The emulator is loading, please wait..., but nothing will happen.

What could be causing this, and how can I get my PhoneGap project working correctly with the simulator?

i found that the problem in java-version

i used java7 - and it cause this problem

i tried java 6 update 25 and it works fine

thanks
