Wassup is a small applet that let's you know what's up with your Java environment. It will tell you the System Properties, as many as the Security system will let you peek at. This includes such things as which JVM is running, which version of Java, which vendor. It may be run as either an Applet or an application.

This Applet will show you all the Java system properties. This will help you diagnose problems with the CLASSPATH, which JVM vendor and version you are getting, your time zone, etc. Wassup is also available with Java source to download. When you run Wassup as an application it shows you considerably more information. The Java sandbox considers it a security risk to reveal that information to an Applet.
