Dear All
I admit that I am new to this all.
I am trying to run a simple login function.

I have two jsp files, login.jsp and welcome.jsp and I have one servelet login.java

My project name is onjava (I am doing this from an example from the web).
My directory structure is the following:

/onjava
/onjava/WEB-INF/classes/com/onjava/login.class
/onjava/WEB-INF/classes/com/onjava/login.java
/onjava/WEB-INF/lib
/onjava/WEB-INF/web.xml
/onjava/images/login_img.gif
/onjava/login.jsp
/onjava/welcome.jsp

The contents of login.jsp are:

<html><head> <title>OnJava Demo</title> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"></head>    <table width="500" border="0" cellspacing="0" cellpadding="0">     <form name="loginForm" method="post" action="servlet/com.onjava.login">     <tr>      <td width="401"><div align="right">User Name: </div></td>      <td width="399"><input type="text" name="username"></td>     </tr>     <tr>      <td width="401"><div align="right">Password: </div></td>      <td width="399"><input type="password" name="password"></td>     </tr>     <tr>      <td width="401"> </td>      <td width="399"><br><input type="Submit" name="Submit"></td>     </tr>     </form>    </table></body></html>

The contents of web.xml are:

<?xml version="1.0" encoding="ISO-8859-1"?> <!DOCTYPE web-appPUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN""http://java.sun.com/j2ee/dtds/web-app_2_3.dtd"> <web-app>        <servlet>        <servlet-name>login</servlet-name>        <servlet-class>com.onjava.login</servlet-class>        </servlet></web-app>

When I run this small functionality, my login page shows up perfectly, but when I put in the user name and the password, the page opens up with the following message.
---------------------------------------------------------------------------------------
HTTP Status 404 - /onjava/servlet/com.onjava.login

type Status report
message /onjava/servlet/com.onjava.login
description The requested resource (/onjava/servlet/com.onjava.login) is not available.

Apache Tomcat/5.5.17
----------------------------------------------------------------------------------------
I think there is some error in the action of the login.jsp page, I have tried many path options for the servelet, but nothing is working.

Any sort of help is very much appreciated.

hi,

1) servlet mapping is missing as mentioned by (jfdaniel07) user
2) There is no need to mention "servlet" in the url .It may be as follows,
http://localhost:8080/onjava/login
<servlet-mapping>
<servlet-name>login</servlet-name>
<url-pattern>/login</url-pattern>
</servlet-mapping>
