i created a properties file with name "localizationdemo.prperties" contains text i want in the language used and i put this file in src folder.

when i run the application and click link that generates the report the following exception "net.sf.jasperreports.engine.JRException: No input source supplied to the exporter."

Note when i run the application in debugging mode i have the following exception details :
"java.util.missingresourceexception can't find bundle for base name locale en_us"
