What URI do you use to invoke the servlet? When you use relative URIs in a page
that you forward to, like you do for the two JSP pages in A.html, the browser
interprets them as relative to the URI used to make the original request.
So if you invoke the servlet with a URI like /servlet/foo, the browser will
try to get the JSP pages with URIs /servlet/B.jsp and /servlet/C.jsp.
The solution I prefer is to define an URI mapping for the servlet so it
can be invoked with a URI that matches the path to the JSP pages. For instance,
if the URI for B.jsp is really /someDir/B.jsp, I define a mapping for the
servlet like /someDir/foo. The browser is then able to construct the correct
absolute URI from relative URIs.
For details about how to define URI mappings for a servlet, see your servlet
container documentation or the Servlet 2.2 specification (the Web Application
Deployment Descriptor section):
