Java Web Start is the preferred method for running the TopCoder Arena but was not automatically detected on your machine. However, Web Start is bundled with all Java versions 1.4.1 and higher. If the Web Start link below doesn't work, try running the arena as a Java Applet.
If you have problems running the arena as a Java Web Start application, you can try running it in the web browser as a Java Applet.
