From the exception I understand that there is some field in the report that points to field "ContactDesignation" from the DB, which is unregistered in the report, or missing from DB.

Try using GUI tools for jasperreports. I worked with  http://ireport.sourceforge.net
There are convenient options to design the reports.

Hope this helps.
