I am fairly new with JSP.  I have Tomcat 3.2.3 running.  When I go to view
the examples, I receive this error below.  I gather that it is not seeing
the main method.  I have both JDK 1.3.1 and j2sdkee1.2.1 installed.  Did
Tomcat not find the JVM that it needs?  When I run the servlet examples I
have no trouble with them.  Please help.



Kindly,

Peter
