1. Why can't I see the GUI interface on my machine?

2. What is Java Plug-in ?

A:

   Java Plug-in software enables enterprise customers to direct applets or JavaBeansTM on their intranet web pages to run using Sun's Java 2 Runtime Environment, Standard Edition (JRE) instead of the web browser's default virtual machine. Java Plug-in technology is part of the current version(1.4.2) of the Java 2 Runtime Environment, Standard Edition. Sun's JRE provides a Java CompatibleTM environment for today's widely adopted web browsers. That means consistency and reliability when running applets.
