I have a class created: com.myapp.util.MyClass which reference a file.txt located in resources folder:


The project is created in eclipse. After I export the project as runnable jar I try to execute the jar and I get a null InputStream.

Could you guys please tell me what else is to be configured (something in the MANIFEST file probably... :| )
