Hi.

A sample can running in Jbuilder3(appletviewer) but happen errors on IE.

That sample is EarthApp.java on java3d tutorial.

I guess when load the Earth.jpg that error happen.I dont know why.The Earth.jpg is in same directory.

I using IE5 and Netscape 4.6.Does that can not load image with TextureLoader?

follow is code fragment

        String filename = "earth.jpg";
        System.out.println("attempt to load texture from file: "+filename);
        TextureLoader loader = new TextureLoader(filename, this);
        ImageComponent2D image = loader.getImage();

The error message is on IE java console.

Error: in loading image
