                    frame.setVisible(true);
                }
        }

I added the executable jar file for JGraphx to my eclipse project and ran this code. But the error is as Exception in thread "main" java.lang.Error: Unresolved compilation problem: 

at com.mxgraph.layout.orthogonal.model.Graph.main(Graph.java:47).

Is this an installation problem or problem with the code?

  • I followed the same procedure of importing a jar in Eclipse but still this error comes up. – raj Oct 20 '17 at 12:20
  • Add the full message/stacktrace of the error and point which line is the 47 – Marcos Vasconcelos Oct 20 '17 at 12:23
  • @MarcosVasconcelos I could succesfully run the program on Eclipse. But when I run it on CMD using javac -cp command the program succesfully compiles but on running it gives JNI error. Can someone help please? – raj Oct 20 '17 at 17:58
  • To run a jar with JNI you need to add the .dll/.so into classpath in the run command (dont remember how) – Marcos Vasconcelos Oct 20 '17 at 18:07
