Can't run JME

Troubleshooting General Help
1

So I started to work with it in NetBeans 6.7 I followed this tutorial to set it up

http://www.jmonkeyengine.com/wiki/doku.php?id=setting_up_netbeans_6.7_for_jme_2.0

and when I run it with this code:



package test;

import com.jme.app.SimpleGame;
import com.jme.math.Vector3f;
import com.jme.scene.shape.Box;

public class TestSphere extends SimpleGame {
    public static void main(String[] args) {   
        TestSphere app = new TestSphere();
        app.setConfigShowMode(ConfigShowMode.AlwaysShow);
        app.start();
    
    }
    @Override
    protected void simpleInitGame() {
        Box b = new Box("My box",new Vector3f(0,0,0),new Vector3f(1,1,1));// Make a box
        rootNode.attachChild(b);// Put it in the scene graph
    }
}




I always get this error:

i don't use netbeans, but in eclipse you need to set a native library path for the lwjgl.jar, which tells it  where the lwjgl.dll can be found.



Having a look on the netbeans tutorial, i guess you should recheck this step:


Next we add all native dynamic libraries to the Java Library Path:

  1.
     In the Project window, right-click your project and choose Properties from the context-menu.
        1.
           Go to the Run category of the Properties window.
        2.
           VM Options: Enter into the VM Options field where to find the native libraries.

           -Djava.library.path="../JME2/jME_2.0_Complete_(r4093)/lib/natives/"

  2.
     Close the Properties window.
  3.
     Your project is now set up to run an applications built with the jME framework.

Hha I did and I got it working I saw the graw box.





Now I have a new problem when I was working with a test file on of the imports in it, NetBeans claims I do not have it



import com.jme.scene.state.AlphaState;

Netbeans is right, you dont have it - that was from JME1 :slight_smile:



See the wiki for how to update JME1 code to JME2

AlphaState is a class belonging to jme1.

… it's suggestet to work with jme2 nowadays… but that just by the way.



what causes your error is a missing import of the class alphastate or you try to use old jme1 code with your netbeans project which is setup for jm2. so it can't find a class alphastate… its not there of course.
