JSDK2.1 on WinNT base (IIS+Proxy)

I am having Window NT 4.0 Based server  on which IIS and proxy are installed in my organisation. I have hosted one web site also on this server. For on line data base access through this web site I have to run servelts.  I am having JSDK2.1 downloaded from sun site. When I copy this JSDK2.1 direcotry  and start JSDK server  using "startserver" command from prompt , server it started . But when I access any servelt using http://localhost:8080/servlet/???? it fails showing page not found. Class fies are copied in  directory "c:\jsdk2.1\webpages\web-inf\servlets" . And default directory of web site is "c:\inetpub\wwwroot"  . 

JSDK2.1 and Servelts are working fine on one of the proxy node . But keeping servlets and data bases on node is not beneficial since data bases can only be viewed from internal network . 
To view data bases from Internet throgh  our web site  we have to run servlets  on the server and keep data bases on the server.

Can any one suggest how to isntall  JSDK2.1 on this server (NT4.0+IIS+Proxy) so that I can run servlets successfully. 
For any clarifiction please write.

Thanks
