Exactly that's what is so confusing because it shows up but yet it gives me that error posted above.

Do you have any clues as to why this might be?

Ok now it compiles and creates the xml and jar files, i can see the library under the libs tab, but when i try to declare a variable as the name of the shortname nothing comes up, why is that?

Note that you should not extend AbsObjectWrapper if the class includes an instance field.

My guess is that the actual problem is in the hapi library and the error message is misleading. As a test try to create a new class which doesn't reference the Hapi library and see whether you get the same error.
