HTTP Status 404: servlet configuration?

Question

ive made a webapp and im wondering about the configuration of my folder as well as the web.xml file. the webapp uses a MVC architecture, but im not having much success running it on apache tomcat. i dont know whether the problem is the way ive structured my folders, something is missing in my web.xml file, or the way ive referenced it inside my jsp files.

for some example :the way ive referenced it in my jsp files is

<form id="loginform" action="/servlet/ControllerServlet" method="post">
<input type="button" onclick="<% response.sendRedirect("/servlet/ControllerServlet?action=register");%>"></input>
<a href="servlet/ControllerServlet?action=upload" id="upload"><span>Upload a profile photo</span></a>

my folder structure is :

newApp(dir) {

newApp/images(dir)

newApp/temp(dir)

newApp/(all .jsp files)

newApp/WEB-INF(dir){

WEB-INF/web.xml

WEB-INF/lib(dir){

lib/org.apache.commons.jar

WEB-INF/classes(dir){

classes/(all classes including controller servlet)

my web-inf file looks like this:

<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchemainstance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
version="2.4">
<display-name>AssignmentForum</display-name>
    <servlet>
        <description>
        </description>
        <display-name>ControllerServlet</display-name>
        <servlet-name>ControllerServlet</servlet-name>
        <servlet-class>itc357.ControllerServlet</servlet-class>
    </servlet>

    <servlet-mapping>
        <servlet-name>ControllerServlet</servlet-name>
        <url-pattern>/ControllerServlet</url-pattern>
    </servlet-mapping>

    <welcome-file-list>
        <welcome-file>index.html</welcome-file>
        <welcome-file>index.htm</welcome-file>
        <welcome-file>index.jsp</welcome-file>
        <welcome-file>default.html</welcome-file>
        <welcome-file>default.htm</welcome-file>
        <welcome-file>default.jsp</welcome-file>
    </welcome-file-list>

<context-param> 
    <description>Location to store uploaded file</description> 
    <param-name>file-upload</param-name> 
    <param-value>
         c:\apache-tomcat-5.5.29\webapps\data\
     </param-value> 
</context-param>
</web-app>

the message that tomcat gives me when i try to access a jsp page is

type Status report

message /servlet/ControllerServlet

description The requested resource (/servlet/ControllerServlet) is not available.

cheers for any help yall can give, bundy

Maybe your URL mapping is wrong? Seems to be mapped to /ControllerServlet instead of /servlet/ControllerServlet. — Thilo

Your code should be something like this

<script language="javascript">
 function submitForm() {
       document.getElementById("loginForm").submit();
 }
</script>


<form id="loginform" action="/servlet/ControllerServlet" method="post"> 
  <input type="button" onclick="submitForm();"></input> 
          <a href="servlet/ControllerServlet?action=upload" id="upload">
              <span>Upload a profile photo</span>
          </a>
</form>
