servlet design issue

[Brian McMullan]

Hi,   We're building a large web site using Servlets. It is our first site since switching from Perl based CGI. In designing the architecture, we are faced with the dilemma of dividing our project up into separate Servlets, or running everything from a single servlet.   Since our project is driven by a single template, we would like to generate the HTML from within one Servlet, if possible. It would also be possible to, however,  "chain" several Servlets together to satisfy a request.   Is there a performance advantage to chaining several servlets together? What is the usual practice?   Thanks
