a NullPointerException in an Action class is very common. If you compile your classes with the "-g" option, the stack trace will tell you the actual line number in your code where the error is occurring. The solution is to find the object that's null, find out why it's null, and fix it.

Incidentally, since this is such a generic error, it would have been better if you had included more details: more of the stack trace, indication of when the error occurs, etc.
