Take a look at mxgraph. It outputs xml on the backend and can easily be converted using xslt/xquery to a jpdl. It is unfortunately a "pay for" product, but if that is not an obstacle for you then it is well suited for your needs. It's nothing more than a huge javascript as well, which means GPD in a browser is not that impossible to accomplish. They have demo's of workflow UI interfaces in a browser that are very JBPM-ish. I contacted them early on and got a beta of the product and did some proof of concept work converting their xml output to jpdl some time ago. Unfortunately, people above me didn't want to spend money for licensing the product so we did not pursue it further. Hope that helps you some.
