Unable to get a 'Congratulations Page'

Hi,
I downloaded the TOMCAT 4 on my machine and i installed it in my machine with the help of Installation Instructions they provided.They asked to make the tomcat as the current dir and give the command like this "C:\jakarta-tomcat-4.1.31\bin\startup.bat".And on my browser "http://localhost:8080". IF i give so, then it will display a congratulations page. but i couldn't get this page instead i got some error messages on the page having something like...

type Exception report

message

We have a forum devoted to Tomcat here. I'll move this question there for you.

Why are you starting out with an outdated version?
Did you set all the required environment variables?
If so, did you test them to make sure they're correct?

Make sure that in Environment variables, you have set CATALINA_HOME and TOMCAT_HOME variables to your tomcat home directory (eg; c:\tomcat4.1 ).

And also see that your servlet.jar is set in CLASSPATH variable .(C:\tomcat4.1\common\lib\servlet.jar
