IIS to front Tomcat on JBoss -- newbie

Is there a really simple step-by-step guide to getting IIS to front
Tomcat on JBoss?

The "IIS HowTo" document at http://tomcat.apache.org/connectors-doc/webserver_howto/iis. html
assumes that c:\tomcat is the root directory of tomcat. But the JBoss
installation doesn't have a /tomcat/ directory at all, but rather
three "jbossweb-tomcat55.sar" directories, one for each application
server instance.

I need a "Start here . . . and then do this . . ." approach that would
help a newbie like me to figure out where to put isapi_redirect.dll in
the JBoss installation, and where to go from there.

Is there such a newbie guide out there?

Thanks,
Dave
