(loading *.3ds) Solved

Troubleshooting General Help
1

Okay, I had my lil class to load 3d objects into jme and for a time, it was good. Recently I moved from netbeans 5.5 to 6. and installed jme2 instead of 1, and it stopped working all of sudden.

I have 3ds file in my source package, I tried putting it everywhere, and still I keep getting null pointer exception, I am sure that I am doing something bad, and it is probably obvious, as all my previous mistakes, but I really can't find anything…



Code:

(System.out.println(url); returns null which means it cannot find file, but why? I even tried providing locator with direct link to it and still nothing.)


 
public static void load(String name, Node rootNode)
{

      
MaxToJme maxtojme = new MaxToJme();  //the converter
Node node = null; //Where to dump mesh.
ByteArrayOutputStream bytearrayoutputstream = new ByteArrayOutputStream(); //For loading the raw file
 
// File Path for the model (dump file in toplevel of classpath)
URL url = truck.class.getClassLoader().getResource(name);
System.out.println(url);
      
InputStream is=null;
try {
    is=url.openStream();
} catch(Exception err)  {
    System.out.println("Could not open Model file: "+err);
}
try {
 
    // Converts the file into a jme usable file
    maxtojme.convert(is, bytearrayoutputstream);
 
    // Used to convert the jme usable file to a TriMesh
    BinaryImporter binaryImporter = new BinaryImporter();
    ByteArrayInputStream in=new ByteArrayInputStream(bytearrayoutputstream.toByteArray());
 
    //importer returns a Loadable, cast to Node
    node = (Node)binaryImporter.load(in);
} catch(Exception err)  {
    System.out.println("Error loading model:"+err);
}
 
//attach node to scene graph
node.updateRenderState();
}



And error:


2008-11-25 22:58:39 class truck.Main start()
SEVERE: Exception in game loop
java.lang.NullPointerException
        at truck.Main.load(Main.java:81)
        at truck.Main.simpleInitGame(Main.java:132)
        at com.jme.app.BaseSimpleGame.initGame(BaseSimpleGame.java:527)
        at com.jme.app.BaseGame.start(BaseGame.java:71)
        at truck.Main.main(Main.java:89)



Thanks.

Ultimately I used this to load my 3ds file:



public static void load(String name, Node rNode)
{

      
MaxToJme maxtojme = new MaxToJme();  //the converter
Node node = null; //Where to dump mesh.
ByteArrayOutputStream bytearrayoutputstream = new ByteArrayOutputStream(); //For loading the raw file
 
// File Path for the model (dump file in toplevel of classpath)
//URL url = Main.class.getClassLoader().getResource(new File(name)).toURI().toURL());
URL url =  Main.class.getClassLoader().getResource(name);
try {
 url = (new File(name)).toURI().toURL();
} catch (MalformedURLException e) {
        }
//System.out.println(url);
      
InputStream is=null;
try {
    is=url.openStream();
} catch(Exception err)  {
    System.out.println("Could not open Model file: "+err);
}
try {
 
    // Converts the file into a jme usable file
    maxtojme.convert(is, bytearrayoutputstream);
 
    // Used to convert the jme usable file to a TriMesh
    BinaryImporter binaryImporter = new BinaryImporter();
    ByteArrayInputStream in=new ByteArrayInputStream(bytearrayoutputstream.toByteArray());
 
    //importer returns a Loadable, cast to Node
    node = (Node)binaryImporter.load(in);
} catch(Exception err)  {
    System.out.println("Error loading md3 model:"+err);
}
 
//attach node to scene graph
node.updateRenderState();
rNode.attachChild(node);
}
