Can't get sample application to run in Simulator

Every time I try to run the sample application from BlackBerry on Adobe Flash Builder, I'm getting this error:


"Error occurred while packaging the application:

Packaging failed:1

Any idea what's going on? I've already updated my java to 1.6, but that didn't fix it. I am also on a Mac computer.

You have to install java 1.6 to use SDK

Any chance you're using dropbox to sync your files?

Launch finder and go to Applications/Utilities and then run Java Preferences.


From there in the General tab you should see a java version 1.6.  Drag this to the top of the list so that it will be the default used.
