3.0.4 Upload Failure HTTP: 500

[Robert Steinmetz AIA]

I have just installed OpenMeetings 3.0.4 on Ubuntu 12.04. I am going 
through trying to verify that everything is working.

I have created some users and they can login. They users can write to 
the Whiteboard. However when I try to upload any file I get a progress 
bar followed by a HTTP: 500 error. The only log entry I can find that 
relates to file I'm trying to upload is below. I've tried PDF's and .odt 
file with the same result. It appears that the upload is not succeeding 
at all.

I gather the files are supposed to end up in 
/opt/red5/webapps/openmeetings/upload/files/ When I checked the was no 
files directory so I created one.
