I am integrating class file (createGraph.java) into a project where i am trying to call my createGraph's main method. I have added third party jar (Nlview.jar) into build path. When i run createGraph.java class it runs perfectly but when i call createGraph.java from existing project it throw exception
CreateGraph.main(arg);
it throw this exception
java.lang.NoClassDefFoundError: de/concept/nlview/NlviewException
what should i do
