Re: [JAVA3D] j3D detection

[Paul Byrne]

Hi Andrea,

Here is the code I use to check if Java3D is installed. I also go on to check
the version number of Java3D is correct for my app

        Package p = Package.getPackage( "javax.media.j3d" );
        String version = p.getImplementationVersion();

        if (version==null) {
            javax.swing.JOptionPane.showMessageDialog( null, "Java 3D can not be
found, please reinstall Java3D 1.3.",
                "Java 3D Not Installed", javax.swing.JOptionPane.ERROR_MESSAGE
);
            System.exit();
        }


Rgds
