Question

If the urlPatterns controls basic URL rewrite, can I not use .htaccess to rewrite the URL? I’m looking at this code: http://www.objectdb.com/tutorial/jpa/eclipse/ee/servlet

...
@WebServlet(name = "GuestServlet", urlPatterns = {"/guest"})
public class GuestServlet extends HttpServlet {
...

This page works great when I access http://localhost:8080/Guestbook/guest, but what if I wanted to do http://localhost:8080/Guestbook/guest/edit?id=4, how would I set that up in this controller?

In PHP the logical steps would be http://localhost:8080/Guestbook/controller/function. In java it seems like I can only use doGet(), is this right?

I’m trying to envision how the overall URL structure affects the execution of controllers.

Answer 1

resource http://tomcat.apache.org/tomcat-7.0-doc/servletapi/javax/servlet/annotation/WebServlet.html

basically you need to change

@WebServlet(name = "GuestServlet", urlPatterns = {"/guest"})

to

@WebServlet(name = "GuestServlet", urlPatterns = {"/guest", "/guest/edit"})

now your servlet should handle the “/guest/edit” URL pattern also
