Why does this code not work?
I keep getting some ugly exception about missing classes. I'm using all the jar files contained in
the .tar download of M6. See below for code and error message. What .jar file am I missing?
package org.mikemccutcheon.sandbox.java3d.cubeworld;
import java.io.File;
import java.io.FileReader;
import java.io.FileNotFoundException;
import javax.media.j3d.SceneGraphObject;
import org.web3d.j3d.loaders.Web3DLoader;
import org.web3d.vrml.nodes.VRMLScene;
import org.web3d.vrml.nodes.VRMLNodeType;
import org.web3d.vrml.renderer.j3d.nodes.J3DWorldRootNodeType;
public class X3DUtil
{
public SceneGraphObject loadX3D(String inFileName)
{
File file = new File(inFileName);
FileReader reader = null;
try
{
reader = new FileReader(file);
}
catch(FileNotFoundException fnfe)
{
fnfe.printStackTrace();
System.exit(1);
}
Web3DLoader loader = new Web3DLoader();
loader.load(reader);
VRMLScene scene = loader.getVRMLScene();
VRMLNodeType baseRootNode = scene.getRootNode();
J3DWorldRootNodeType rootNode = (J3DWorldRootNodeType)baseRootNode;
SceneGraphObject sceneObject = rootNode.getSceneGraphObject();
return sceneObject;
}
}
error:
