[xwiki-users] New installation - XAR upload failing

I'm a first time installer, running 1.3M2 and trying to upload the XAR file. I'm getting the following error in the xwiki.log file (which, oddly, is in the tomcat base dir instead of the tomcat/logs dir). Also, when I try and create users, the form submits, but it doesn't appear to be saving because no users are listed after 'save'. I'm running on linux, MySQL 4.1 and JDK 1.6. The DB was created successfully and I was able to edit the front page. Any ideas? Should I try 1.2 instead?
