I installed Coldfusion Developer Edition, which I understand can run JSP files with JRun. When I try to do so, however, I receive a "500 null" JRun Servlet Error. The file can be completely empty and I'll get this same error. As you can imagine, this makes it quite difficult to incorporate JSPs into my Coldfusion application, and any help would be greatly appreciated. Most maddening is that the same file will work on a colleague's machine but not my own, even after reinstalling Coldfusion/JRun. This is what shows up in the coldfusion-event.log file:
