Apache Tomcat/6.0.18

The stack trace contains: Could not parse mapping document from resource events/Event.hbm.xml

This suggests that the problem is in your mapping file: Event.hbm.xml.

Further down in the stack trace you also see the following:
Error on line 2 of document : White spaces are required after keyword PUBLIC in DOCTYPE decl.

This tells you where in the file the problem is, and what it is.
