Load Models From Outside Classpath?

Troubleshooting graphics
1

I'm trying to load models from outside of the filepath by using a FileDialog…



This is what the code essentially looks like, it's just spread out over a few classes.  (yes, the information is getting from place to place correctly…


// first
if(fileDialog.getFile()!=null){
     File fileToConvert = fileDialog.getFile();
}

// later
ColladaImporter.load(fileToConvert.toURI().toURL().openStream(), design.getName());




I get this error after an NPE in the console:
baseDir can not be null


Any ideas?  I normally use the ResourceLocator tools when working off the classpath, but we're looking to load in models from users, so it's kind of tough for them to have the COLLADA's on the application's classpath :)

Can you post the whole stack trace?

Sure, this is my current problem: (the baseDir can't be null was when I tried using ResourceLocators, but this is 'more correct')

Textures are in the same folder as the .dae, same results using './texture.jpg' or 'texture.jpg'

For kicks, here's the function that loads the model:


public static Node ColladaLoader(final IGenericDesign design, final IGPSCoordinate centerMap, URL modelURL) {
      Node modelNode = new Node(design.getName());
      try {
         ColladaImporter.load(modelURL.openStream(), design.getName());
      } catch (IOException e) {
         ErrorDialog error = new ErrorDialog();
         error.setVisible(true);
         error.setError("Could not load model!");
      }
      modelNode = ColladaImporter.getModel();
      modelNode.setModelBound(new BoundingBox());
      modelNode.updateModelBound();
      return modelNode;
   }

Solved.



I tried using the AbsoluteResourceLocator from blaine but didn't have much luck…  After a few more hours of tinkering, I came up with this:



ResourceLocatorTool.addResourceLocator(ResourceLocatorTool.TYPE_MODEL,
               new SimpleResourceLocator(modelURL));
         ResourceLocatorTool.addResourceLocator(ResourceLocatorTool.TYPE_TEXTURE,
               new SimpleResourceLocator(textureURL))
         ColladaImporter.load(modelURL.openStream(), design.getName());



Aye, it is simple.. should've done that long ago.  But it works and I hope someone in distress find this useful someday :)
