Exception: java.lang.NoClassDefFoundError thrown from the UncaughtException

Question

Exception in thread "main"
Exception: java.lang.NoClassDefFoundError thrown from the UncaughtExceptionHandler in thread "main"
I dont know why, but after 3 hours of processing I get this error. I encapsulated my main with try/catch but nothing is caught. Nor is there a traceback.

Answer 1

I don't have any idea to offer on what the problem is. However, here are some suggestions:
Perhaps you can provide an example of your code and/or a more through description of what it does so someone might see something wrong with the code.
I assume you print out the entire stack trace using somthing like this, so you can get the entire stack trace:
} catch (Exception e) {
e.printStackTrace();
and not something like this:
System.out.println( e.getMessage());
You can also consider peppering your code with System.out.println() statements (or write to the log file) to get a better understanding of whats going on and where it crashes.
What is jgps.RTI.jar? Is that a jar file you created or a vendor jar file? If its a vendor jar file, you might research their web site on how to use it.
