I have a project that involve using Commons-lang. I downloaded the bin and make the whole process of creating the User Library for adding it in another projects.
Everything works fine using Eclipse IDE, but when I want to Export the project as a Runnable JAR. The actual project starts but doesn't make the functionality related to the Commons-lang library.
When I execute it with Command line I got this errors
Error messages from JAR file in CMD
I'm using the option of Package required libraries into generated JAR.
I want to know what conf I have to change to make the actual Runnable JAR fully functional.
