[Building Sakai] Urgent Help

[Matthew Jones]

I've never seen this before. I would check to make sure your tomcat is
configured with the proper URIEncoding parameter in the server.xml for
either ajp or direct connection. It seems like this could cause this problem
depending on what characters are used. This page isn't very prominent. If
you've already got this setup correct, someone else can offer a step #2. ;)
