Any Idea Anything Missing – workbench 7.0 issue

[Brian Fernandes]

You need to provide Jersey with further information it needs to be able to serialize and deserialize your ProcessDefinitions list.

I would recommend reading this chapter for information: http://docs.sun.com/app/docs/doc/820-4867/ggnxo?l=en&a=view specifically look at the MessageBodyReader and MessageBodyWriter classes.

Hope this helps.
