Could anyone help me?

I have installed Tomcat 4.1.12 and successfully configured to run JSP in
browser through IIS.

But I have planned to use SHTML instead. After I have create SHTML with JBuilder
7, a file "webserverglue.jar" has been set into "web.xml"
I can successfully run the SHTML in the development environment in JBuilder.
When I deploy it to the TOMCAT server with IIS, I can only run it within
Tomcat (i.e. http://localhost:8080/...), but cannot run through IIS (e.g.
http://localhost/...) (with error "Page cannot be found!")

Can anyone tell me why this happened?
webserverglue.jar cannot be loaded?
should I enable TOMCAT SSI or CGI?

Thanks.
