Publish report error

I'm trying to publish my report from Pentaho Report Designer and I'm receiving an error which is directing me to see the server logs. After looking at the pentaho.log file that is found in the tomcat logs directory under the biserver-ce directory it gives me the following message which I'm unable to decipher. I am new to PRD and would appreciate some direction. I was not sure which log file to investigate and assumed this was the correct one.

Report designer 3.8.2/Mac OSx 10.7.5

log file message - Pentaho.log (biserver-ce-4.8.0-stable/biserver-ce/tomcat/logs/pentaho.log)
