The approach I use is to map my controller servlet to a filename extension with an
entry like this in the web.xml file:
<servlet-mapping>
<servlet-name>MyControllerServlet</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>
which associates the ".do" suffix (implying "go do something") with the controller
servlet. Now, my JSP pages can submit to a URL like "listCustomers.do" or
"addOrder.do" and my controller servlet can do this:
String matchPart = request.getServletPath();
int extension = matchPart.indexOf(".");
if (extension >= 0) // Strip off the extension so I can change it at will
matchPart = matchPart.substring(0, extension);
Given the two above examples, I would get a string of "/listCustomers" or
"/addOrder" from this code, and I can use the matchPart value to look up the
appropriate action class.
