[jgrapht-users] Help needed

[Pratik T. <tib...@gm...>]

Hello,
I was trying to run the HellopGraphT code present in the Wiki - link
<https://github.com/jgrapht/jgrapht/wiki/HelloWorld> . There was one typo
which I have rectified in the wiki. At present the code is getting build
and targets are generated fine. But while running the class file I am
getting the following error:

Error: A JNI error has occurred, please check your installation and try
again
Exception in thread "main" java.lang.NoClassDefFoundError:

If someone can help me then it will be great. Thanks in advance.
