[rules-users] get image of flow from xml

I'm trying to show an image of a workflow on a web page, based on it's xml. I've first tried to do this by using drools-eclipse project functionality of export workflows as images, but gave up because the project has many dependencies. Then I tried the drools-guvnor, which do exactly what I want, but it's developed using GWT. My problem i'm having now is with using drools-guvnor jar in my GWT project, and then i'll still have to integrate it with SEAM. I want to know if this can be done. Have someone already done this before? Is there a better way?
