Adding resourse bundles and external jar files: This may not be the same version as the asker, but in Jaspersoft Studio 6.0.3 I solved the same problem I was having by creating a folder names resources in the My Reports folder. I put all my message_*.properties files and *.jpg files in it. In Jaspersoft, in the Project Explorer: --> right click resources --> Build Path --> Use as Source I also create a folder named lib and put a util.jar file in there that contained some util classes. Then, in a similar way --> right click util.jar --> Build Path --> Add to Build Path you can get to the general build/source configuration menus by right clicking pretty much any element in the explorer and picking --> Build Path --> Configure Build Path... after that EXIT and RESTART the Jaspersoft Studio!!
