I'm having an error like this in my stacktrace, how do I fix this?

Exception in thread "Thread-4" java.lang.NoSuchMethodError: com.bulletphysics.collision.broadphase.OverlappingPairCache.setInternalGhostPairCallback(Lcom/bulletphysics/collision/broadphase/OverlappingPairCallback;)V

I've already added the jme-bullet project in my build path, whereas the tests in that project works… am I missing something?

I'll try that… by the way, I'm using the project which I downloaded from the svn repository into my Eclipse IDE… I'll try adding the libraries manually first… then if it fails, I'll get back to you…thanks for the quick replies

Mhelz0001,

If your project compiles, then you have setup your compile-time classpath correctly.

As the problem was encountered you tried to run the project, that indicates the runtime classpath is not setup correctly.
You are going to encounter the same runtime problem however you choose to implement the PhysicsGameState, until you setup the runtime classpath correctly.

I have already added the whole project folder of jbullet in my classpath

If you have have added the entire jbullet project (jbullet != jbullet-jme) on both the compile time and runtime classpath you will not get the problem from the first post

Exception in thread "Thread-4" java.lang.NoSuchMethodError: com.bulletphysics.collision.broadphase.OverlappingPairCache.setInternalGhostPairCallback(Lcom/bulletphysics/collision/broadphase/OverlappingPairCallback;)V

the real problem I'm having is in jBullet's classpath… as aforementioned

Yes, the problem is that jBullet is not on the classpath being used at runtime by your project. 

I can run the tests in the jmetest folder of jbullet-jme in my eclipse ide… however, I can't seem to make it work in my project

I believe I understand now, you don't have jBullet jars on the classpath at all. The project compiles without problem because you are not directly accessing the jBullet methods (as that is done by jbullet-jme).
The jbullet-jme tests are running fine as the jbullet-jme project has the necessary libraries correctly setup.

All that is need is to add the jbullet jars onto the runtime classpath of your project. There are various ways to achieve this, one of them being to add them as library JARs to your project.

The jars are located within the jbullet-jme project:
