I am working on a Blackberry App using Eclipse Galileo and all of a sudden I can't run the app in the simulator. There's nothing particularly strange about the app and until I closed Eclipse and started it again it was running perfectly fine. But now it won't run. The icon in the Downloads folder has gone to the default instead of the one we use for our app, and when I try and run it I get this error:

Error running [my app]: Can't find entry point.

I have tried everthing but can't for the life of me figure out what on earth is going on here. Again: all I did was restart Eclipse and have been unable to run the app ever since.

Can anyone help please? What is an entry point in any case?

Clean your Simulator and and Build and Debug your Application.

Or try for another Simulator.

Check your BlackBerry Packaging Console (at the bottom of the screen there's an icon of a blue computer screen with a down triangle next to it. Click that)

If you see the message "java.lang.StringBuilder: Warning!: No definition found", that might be the problem. I'm not sure where the problem comes from or how to solve it, but as a work around, you can find all references to the String + operator and replace them with StringBuffer.append.

Try setting your Compiler compliance level to 1.4 (Window->Preferences->Java->Compiler). For some reason after installation my level was set to 1.6. Moving it down to 1.4 made the error go away for me.
