I add a barcode to my report using the bacode element from the pallet.
When I compile the report and run it in my web application I get a console message:
net.sf.jasperreports.engin.component.ComponentsEnvironment findBundels Found two components for namespace http://jasperreports.sourceforge.net/jasperreports/components
If I remove the barcode element from the report this message does not appear.
