Sure it is. I am not sure if its possible in Servlet 2.1/2.2 to "path map"
to a specific controller servlet, but I think it is. I use extension mapping
myself. But basically you would do something in your web.xml file like:
<servlet>
<servlet-name>controller</servlet-name>
<display-name>controller</display-name>
<servlet-class>com.mvc.servlets.ControllerServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>controller</servlet-name>
<url-pattern>/ss/</url-pattern>
</servlet-mapping>
Now, anytime the /ss/ appears in the request path, it should pass everything
after the /ss/ as path info to the controller servlet its mapped to. Thus,
anytime the /ss/ is in your path, the servlet you map it to is invoked, and
I think the request.getPathInfo() or one of those calls returns everyting
after the /ss/. Therefore, a link like:
<a href="/web-app-context/ss/DoThis">Click</a>
Should call your servlet, and you would recieve a DoThis as a String
parameter or something.
Once you have that, you call upon your EJB session bean (or some business
logic class) that looks up in the database and returns you a path to go to.
Then you simply do:
try
{
request.getRequestDispatcher(url-from-database).forward(request,response);
}
catch(Exception e)
{
}
That will forward you to the new URL.
Ask if you have any questions..but that should help a bit I hope.
