During the General Session at JavaONE a fully functional 3D application with (3D)-sound support was presented. The interesting thing is: it ran on a cell phone with a NVidia graphic card usind OpenGL.
The openGL binding was migrated from desktop to Java ME - it ran smoothly. If you like to start with OpenGL - there is a OpenGL Pack for Netbeans freely available for download. It is already one of the most popular Netbeans extensions. It comes already with samples and full documentation.
NEW: Online Workhop Effective WebApps without Frameworks is also coming to: MUC Airport.
