I have started building the JSR-168 IMSTI portlet. The first challenge was getting a file uploaded in through JSR-168. I was nervous because I had never tested it in the Sakai JSR-168 and the first google searches of “JSR-168 portlet file upload” seemed to indicate problems and kept talking about Apache commons, etc – all stuff that felt rather non-portable.
The solution was found here:

I will soon check this into SVN in contrib. On to the next thing – parsing the IMS TI descriptor with some code tha Anthony wrote.
