JAAS started out as an extension to the Java 2 platform, Standard Edition. Recently, however, it has been added to version 1.4. To complete this tutorial you will need the following:

• JDK 1.4, Standard Edition
  
  
• The tutorial source code and classes, JavaSecurity2-source.jar, so that you can follow the examples as we go along.
  
  
• A browser that supports the Java 1.4 plug-in.

You can use JDK 1.3.x, but you must install the JCE and JSSE yourself.
