Java servlets on Tomcat take to 404 error but it works fine on localhost

Tags: , , ,

I have design a webApp with NetBeans IDE. It works fine on localhost, but when I deploy it on my host, trying to access the servlets give me a 404 error.

My servlet dos include the URLpattern and the Name specifications, like this

@WebServlet(name = "FAQ", urlPatterns = {"/faq"})
public class FAQ extends HttpServlet {

The servlet just does a “redirection” to a .jsp

    protected void processRequest(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        request.getRequestDispatcher("/faq.jsp").forward(request, response);

If I use the URL www.mysite/faq.jsp it works ok, but it doesn’t when I try the servlet www.mysite/faq (even it does on localhost, as I said).

I have checked the .class files are compiled and included on the WEB-INF folder and it doesn’t seme to be the problem.

Also I tried to add the web.xml description of the servlet like below, but it doesn’t work either.

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" xmlns="" xmlns:xsi="" xsi:schemaLocation="">

I don’t know waht could be my problem and it may be a very stupid thing, but I can’t find it.

Thank you all.



As I said, it should be a simple thing. The hosting server was configurated on Tomcat 10x and JDK 10, while my project was build on jdk 8 and tomcat 7. The solution was to ask for the hosting provider and change the server configuration to fit my project.
