JSP won't load but servlets do
Hi,
I have installed a Jakarta Tomcat web server on a Windows 2000 server
machine.
To do that I have installed the JDK 1.3.1 and added the environment
variable.
Then I installed Tomcat 4.0.2 and added the environment variable.
I can properly load the server main page by going to http://localhost:8080/
in this page I can test any servlet example : they are all working
But when I try to use any JSP example I have an exception(http 500) :
type Exception report
message Internal Server Error
description The server encountered an internal error (Internal Server
Error) that prevented it from fulfilling this request.
exception

It used to work well before and I don't see anything wrong with my install,
do you ? Is it because I am using Windows 2000 where I used to run Windows NT
?
Thanks for your help

Raphael,
The real problem is this:
java.lang.NoClassDefFoundError: sun/tools/javac/Main
This means that the tools.jar file is not in Tomcat's classpath. Tomcat
will look for this file in the %JAVA_HOME%\lib directory. If there is no
tools.jar file in that directory, your problem is one of the following:
1. %JAVA_HOME% is set to the JDK's "jre" subdirectory - If this is the
case, reset %JAVA_HOME% to the parent directory of your current
%JAVA_HOME%.
2. %JAVA_HOME% points to a JRE installation - If this is the case (i.e.
if there is no javac.exe command in your %JAVA_HOME%\bin directory)
you need to install the full Java 2 SDK since Tomcat needs the javac
compiler.
