As always, thank you for the complete response. It worked.
I did see that particular method in Eclipse's content assist, but I think I didn't use it correctly or something.
What irks me is the obtuse manner in which key aspects of Camunda are documented. They assume far too much about the people trying to use it. I love the product and Camunda itself is great to work with, but this is what comes when you have a company full of coders. They need less brilliant people.
