Tomcat - IS Install Issue - WmSamples JSP not working too

, ,
1

Hi,
This is my first attempt to work with JSP on IS(IS_6-5_SP2) installed on my desktop. I tried working with the JSP provided in WmSamples and that too fails with the below error. Any pointers on what could be going wrong here
TIA,
AK

Do you have the “tools.jar” of the java you are using to compile your JSP’s in your class library?

Thanks for the response. The issue here was with servlet.jar
When things don’t work you try many things - in one of the posts on this forum - it was mentioned to copy the tools.jar and servlet.jar to C:\wm6\IntegrationServer\lib\jars among many other things - so after everything else was in place servlet.jar was the piece that was giving the trouble - I deleted it and the issue was resolved - a quick search on google for the error helped.
