Hi Creature,

verify the rights of the Tomcat temp folder. Look at this thread:
http://community.jaspersoft.com/questions/543492/javaioioexception-problem-reading-font-data

Please, before add a bug to this tracker put your question in the forums, many times it is not a bug or it's a bug of a third party library. This tracker is a TODO list for OpenXava core team, so must be things that we can fix in OpenXava code.
