Tomcat & Jsp

[Djamel Djem]

Hi Friends,
Please Help me.
I have installed Tomcat. I have set the environment variables as :
SET JAVA_HOME=C:\JDK1.3
SET CLASSPATH=C:\JDK1.3\lib\tools.jar;C:\jakarta-tools\servlet2-.2.0.jar;%CLASSPATH%;
SET TOMCAT_HOME=C:\jakarta-tomcat-3.2.1
SET PATH=$JAVA_HOME\bin;%PATH%
When I enter http://localhost:8080 I get the home page, but My problem is when I try to run JSP file from Tomcat examples folder I receive the following error :
Error: 500
Location: /examples/jsp/num/numguess.jsp

Do you possibly have an earlier version of servlet.jar hanging around? Maybe in JAVA_HOME\jre\lib\ext directory?

SET CLASSPATH=C:\JDK1.3\lib\tools.jar;C:\jakarta-tools\servlet2-.2.0.jar;%CLASSPATH%
What is that "servlet2-.2.0.jar" doing in your classpath? Tomcat comes with its own servlet.jar, in the tomcat/lib directory. Why not change the AUTOEXEC entry to use the Tomcat version.
