	As this error indicates, Tomcat can not find javac
(java.lang.NoClassDefFoundError: sun/tools/javac/Main).  This indicates that
you have not set your JAVA_HOME variable or have set it to the wrong path.
(It needs to point to the directory that contains lib/tools.jar).

Subject: error: 500


Hello,

    I've installed Tomcat 3.2.1 (stand-alone) and the JDK1.3, and
started Tomcat using justGo and it all works well. When I connect
to http://localhost:8080/ it displays the default tomcat
homepage. Then I tried to use some of the examples, and it
appears that only the servlet examples work, not the JSP
examples. Each time I want to start one of the JSP examples I get
an error: 500 (complete error message below). What exactly goes
wrong and how can I solve it?
