MIS 3.0 + tomcat

[dreeze]

I'm trying to configure tomcat to run on IIS 3.0.
as i go through the documentation of tomcat, they require that i install a filter called
isapi_redirect.dll
In the documentation they have instructions to do so for IIS 4.0. I realised
that i cant add any filters through the IIS manager (or is there?). so i supposed that that option is not available in my version.
therefore i checked on msdn/microsoft network to see how i can install for my version. they only have it for IIS 1.0, and i did what was there.
basically its adding the path to the .dll file in the filters value in the registries.
my servlets still wont run, with tomcat obviously launched and listening. I don't get any logs for my asapi filter, even though its specified in the reg.

i get a 404 error. the rest of the configuration process was followed to the letter except for the ISAPI filter where I did this manually in the registry.

questions are;
- is this the way we are supposed to put in filters for MSIIS 3.0?
- if so, what could be preventing tomcat from sensing the request and why dont i have a logfile


any thought?
thnx
