I am a newbie to Spring framework especially Spring MVC.
I am writing a code which takes in a Name in a form and displays it on the page. So index.jsp is the form class in which on hitting the sayHello button the request should get forwarded to another page hello.jsp and prints the message. But on clicking the button it is giving 404 error. According to me all the names and configurations are fine but it just doesn't go and prints the message.
index.jsp
<h2>Form</h2>
<form action="./hello.html">
Name: <input type="text" name="name"/><br>
<input type="submit" value="sayHello"/>
</form>

The issue got resolved.
I think the issue was with my system or eclipse itself.
Ran the code on other machine and it worked just fine.
Thanks for replying #alex.b
Check with your directory
make sure that you have build path for required jar files
if it is correct it should work

Please help. Seems to be perfect but I don't know whats wrong. Thanks in advance!
In your web.xml file configuration, you have not mention spring context configuration file location. So spring will not be able to find RiteshMVCDemo-servlet.xml file. Also you have not registered for ContextLoaderListener. Please use below code snippet:
<?xml version="1.0" encoding="UTF-8"?>
<web-app ...>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/spring/root-context.xml</param-value>
</context-param>
<!-- Creates the Spring Container shared by all Servlets and Filters -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<display-name>RiteshMVC</display-name>
<servlet>
<servlet-name>RiteshMVCDemo</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

</servlet>
<servlet-mapping>
<servlet-name>RiteshMVCDemo</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>
root-context.xml and RiteshMVCDemo-servlet.xml should be in the location as mentioned in the configuration

It worked without me changing anything after some time. I do not understand why this is unreliable :(
Is there some best practice ?
Thanks,

I just started learning spring mvc. Trying to follow a hello world sample.
Everything seems to be working fine, except the jsp view is not able to receive the model attribute value set in the controller.
Here's some code.
Controller:

import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
#Controller
#RequestMapping("/welcome")
public class HelloController {
#RequestMapping(method = RequestMethod.GET)
public String printWelcome(ModelMap model) {
model.addAttribute("message", "Spring 3 MVC Hello World");
return "hello";
}
}

Using <%# page isELIgnored="false" %> helped.
We need to include org.springframework.web.servlet.ModelAndView instead of org.springframework.web.portlet.ModelAndView;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
#Controller
public class HelloWorldController {
#RequestMapping("/hello")
public ModelAndView hello()
{
System.out.println("Just Test iNside");
String message = "HELLO SPRING MVC HOW R U";
return new ModelAndView("hello", "message", message);
}

Try this changes may be it will work for you
you can use <th:block th:text="${your_attribut_name}"/>
example controller
#RequestMapping(method = RequestMethod.GET)
public String printWelcome(ModelMap model) {
model.addAttribute("message", "Spring 3 MVC Hello World");
return "hello";
}
view
<h1>Message : <th:block th:text="${message}"/></h1>
output
Message : Spring 3 MVC Hello World
