Jasperreport outputs quiet a bit of debug messages when generating print objects. To get rid of them, edit the
log4j.xml file in your
jboss/server/default/conf directory and add the following lines in the Limit Categories section of the file.
<!-- Limit the net.sf.jasperreports to WARN since logging to DEBUG floods your log with unnecessary messages --> <category name="net.sf.jasperreports"> <priority value="WARN"/> </category>
