Alejandro, thank you for responding. I attempted to add the user library "jBPM Library" to my build path, but received an error/notification that the path already exists.

As you can see, the errors are still extensive. Additionally, the reason I added the comment about the runtime location is because my preferences window doesn't include jBPM at all, even though it's installed.
Any other suggestions? Of course I want to get the GPD working!
