I've done a little digging in the code and was able to track down the changes made by Ole to allow "pluggable" renderers in OpenJUMP. He basically changed to createRenderer() method of the RenderingMananger class. It now looks up the appropriate Renderer to create for an object based on its class name.
I have attached files showing the code for the createRenderer() method in JUMP and OpenJUMP. I have also attached a text file with 2 new methods added to the RenderingManager class by Ole to support this functionality, the getRenderFactoryForLayerable() method and the putRendererForLayerable() method. I haven't gone over Ole's additions word by word, but I think I have a pretty good understanding of what is going on here. If Vivid Solutions is interested in supporting plugabble renderers I can create a submission for the JUMP CVS for David or another Vivid developer to review. I can even make some slight revisions to Ole's code for Vivid's JUMP if some small changes need to be made.
