Change your controller to GET
#RequestMapping(value = "/hello",method = RequestMethod.GET)
public ModelAndView mymethod(){
return new ModelAndView("hello","msg","Hello First Spring");
}
Also change your web.xml
<servlet-mapping>
<servlet-name>spring</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
I am new to Spring MVC and I am converting my standard Web Java project. I am having a problem making the project call a controller by default instead of a JSP page. In the web project before every request was handled by a controller and this doesn't seem to be the case with Spring could anyone advise?
I am using Netbeans and my code so far is below:

Any help would be a appreciated as I have spent two days on this and have got no where. Many thanks
It looks like the controller class is not registered because the package name specified in <context:component-scan> seem to be incorrect. Change it as below and check if it works.
<context:component-scan base-package="com.spring.InternetJavaSpring.Controllers" />
<context:annotation-config />
I am new to spring, trying to run the Spring application through XML configuration, but i am not getting any error in console. But the application is not running and i am getting the 404 error. I didn't add the servlet-api jar in WEB-INF/lib. Can anyone please help me? Thanks in advance.

Your bean definition of the Action is not correct. You have to define a controller bean with some valid name like:
<bean name="helloWorldController" class="com.raistudies.action.HelloWorldAction" />
Then you need to add the url mapping definition to your configuration to map requests to the defined controller.
<bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
<property name="mappings">
<props>
<prop key="/hello.htm">helloWorldController</prop>
</props>
</property>
</bean>
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:
package org.home.webapp.controller;
import org.springframework.stereotype.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
