Wassup software provides an overview of your Java environment, displaying System Properties that can be accessed by the Security system. The information includes details like JVM running, Java version, vendor and more.

When you use Wassup as an application, you can access more information compared to using it as an Applet. The Java sandbox generally considers revealing more information as a security risk when it comes to Applets. This means that limiting the information is considered necessary to prevent potential security threats. However, running Wassup as an application will allow you to see all the possible System Properties.
To access information when using Wassup as an unsigned Applet, you will have restricted access. This restriction means that your view is limited only to specific details. However, if you are willing to override the Java sandbox security, you can view the restricted System Properties. This override option will enable you to access additional information that the sandbox generally restricts.
Overall, Wassup is a helpful software tool that provides you with significant information about your Java environment. It is easy to use, reliable, and comes in both application and Applet versions. The software's ability to reveal more information as an application is useful, even though running it as an unsigned Applet may limit your view.
