HTTP Status 404 - Not Found on call of Servlet

Question

I am getting HTTP Status 404 when i call Servlet from JSP page.

Here is web.xml :

<servlet>
    <servlet-name>Register</servlet-name>
    <servlet-class>servlets.dataio.registration.Register</servlet-class>
</servlet>
<servlet-mapping>
    <servlet-name>Register</servlet-name>
    <url-pattern>/Register</url-pattern>
</servlet-mapping>

Here is effective code of JSP:

<form name="admin-form" action="Register" method="POST">

Error message:

HTTP Status 404 - Not Found

type Status report

message: Not Found

description: The requested resource is not available.

Directory structure is:

Web Pages --> Pages --> Registration --> registerpage.jsp

I have tried Clean and Building project. I am using NetBeans IDE and GlassFish server

Is the JSP file under some folder? It should be just under `Web Pages` since you're using `action="Register"` — lxcky, Sep 25 '14 at 10:32
Then that's why you're getting an error. Please post your directory structure so that I can help you fix it. — lxcky, Sep 25 '14 at 10:34

Servlet package structure is `servlets.dataio.registration.Register.java` — Malwinder Singh, Sep 25 '14 at 10:41

Try:

action="../../Register"

To make your page relative to where the Servlet is.

../ means one directory up. And based on the directory structure you've posted, it's two folders down under the Web Pages so you'll need two ../ to make it relative to where your Servlet is, which is, based <url-pattern>/Register</url-pattern> meaning just under Web Pages

The action attribute is using by default relative path, so if your jsp is available at http://yourHost/yourApp/pathToJsp/registerpage.jsp then your relative servlet path is http://yourHost/yourApp/pathToJsp/Register which is not correct.

You have two choices:

use relative path like J.Lucky suggested - but its error prone, as you have to fix it in every jsp, or if you move jsp in you directory structure
use absoulute path - start with / - but you need to include your context-root name, like this - /yourContext/Register. If you want to avoid hard coding context root you can use request.getContextPath() method, like this action='<%=request.getContextPath()%>/Register'

try action="/Register"
