I'm trying to write a login example that takes the user to a success.jsp if username equals password and an error message if it doesn't. The error message works but success (username=password) results in a 404 (HTTP Status 404 - /Struts2Ch4/success.jsp)
I experienced a similar problem in a previous post. I had not declared the RESULT parameter in the class. I was advised to use annotations in the class file and this solved the problem. In this case both the success and result parameters seem to be declared by the class so I'm not sure why I'm getting 404.

Try to add <%# page isELIgnored="false" %> it will enable EL:

You probably mean:
if (li!=null)
From
if(li==null){
Iterator<Student> it=li.iterator();
while(it.hasNext()){
Student st=(Student)it.next();
int rno=st.getRno();
String name=st.getName();
int eng=st.getEng();
int mat=st.getMaths();
Not sure if that's it, but that will definitely cause a NullPointerException.
Better to use JSTL rather than scriplets in you JSP
e.g.
<%# taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
....
<c:forEach items="${disp}" var="student" >
${student.rno}
${student.name}
</c:forEach>

Try getting the values directly out of the request.
<%
String username = (String) request.getAttribute("username");
String password = (String) request.getAttribute("password");
%>
<table>
<tr>
<td>Name</td>
<td><%= username %></td>
</tr>
<tr>

That should definitely work... if not, something's wrong with the setup.
your command name
commandName="loginform"
is different than model attribute
#ModelAttribute("SchoolManagement")
try to use same names

Now the problem is that when i am doing the login it is working fine and it is generating the URL SpringWebCrudExample/forms/start and coming to this page (the picture i attached here).Now i have added a link call add in this page from which i will go to a page where i will insert some vlaues, but the problem is here when i click on this URL it is giving SpringWebCrudExample/add this URL.As the result the page is not coming.
It has nothing to do with spring but with basic URL generation.
When you are prefixing a href with a / it means that this is an absolute URL and it will be navigated from the root of your application. If you leave it out it will be relative to the current URL.
Now lets take an application deployed at /app which has a servlet mapped at /servlet. If you are in a page at /app/servlet/page and you have a href like /foo it will result in the actual location of /app/foo. Leaving the / would lead to /app/servlet/foo.
For more information see Absolute vs relative URLs

<h1>Hello World from Struts-2</h1>
<s:action name="helloWorldActionSupport" executeResult="true">
<label for="name">Please Enter Your Name: </label><br/>
<input type="text" name="name"/>
<input type="submit" value="Say Hello"/>
</s:action>
</body>
</html>
After I click on the submit button it doesn't proceed to the next page.
Use this code
<s:form action="helloWorldActionSupport" method="POST">
<label for="name">Please Enter Your Name: </label><br/>
<input type="text" name="name"/>
<input type="submit" value="Say Hello"/>
</s:form>
