Java Programming

I designed some reports with iReport / Jasper report. It all works fine while running it under the netbeans IDE, but once I generate a dist and start the application from the .jar file, the reports don't print. I guess it can't find the jrxml and the jasper files. I tried copying the files to various locarions - on the root, inside the .jar file in many different locations (in the root of the .jar, in the .class dir, in a report sub dir with in the class dir, in a sub dir inside the lib dir,. loose with in the lib dir....) and nothing works.
I tried marking the sub-report dir as ".\\reports\\" and also as ".\\" - nothing works...

Where and how should I include those files in the dist package??

Thanks
