Knowledge Spreading : Spring MVC 3.1 and JBOSS 7.1.1

Create “Hello Spring !!!” Using Spring MVC 3.1.2 and JBOSS 7.1.1

Step 1:

Download Spring 3.1.2 jar from below link

https://github.com/SpringSource/spring-framework/tree/3.2.x

Download JBOSS 7.1.1 Final from

http://www.jboss.org/jbossas/downloads/

For installation of JBOSS on windows 7 please refer my previous post

Require Eclipse Java EE IDE for Web Developers. Version: Indigo Service Release 2

Step 2:

Open Eclipse IDE and Create New Dynamic Web project “Springmvcapp” . Copy all Spring Jar to lib directory of Web Content and Also add jstl.jar and common-logging.jar (Download from java2s.com or maven repository)

Note: Important is we need spring 3.1.2 jar for JBOSS 7.1.1

If we try with spring 3.0.1 over JBOSS 7.1.1 following Error will throw at the time of Deployment

java.lang.NoClassDefFoundError: org/jboss/virtual/VirtualFileVisitor

To avoid this error we need to use Spring 3.1.2 jars over JBOSS 7.1.1

Step 3:

Go to src folder and create package com.mahavirdhat.org.controller

And create WelcomeController.java

package com.mahavirdhat.org.controller;

import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.servlet.ModelAndView;

@Controller

public class WelcomeController {

@RequestMapping("/hello.html")

public ModelAndView helloFunction(){

ModelAndView mav = new ModelAndView("hello");

mav.addObject("hello", "Hello Spring!");

return mav;

}

Step 3:

Create index.jsp copy into WebContent folder of project

webcontent/index.jsp

From this Page we can redirect to hello.jsp (hello.html because *.html is configure in web.xml )

Index.jsp

--------------------------------------------------------------------------------
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"

pageEncoding="ISO-8859-1"%>

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<html>

<head>

<title>Welcome To MVC Example </title>

</head>

<body>

<a href="hello.html">Say Welcome </a>

</body>

</html>

---------------------------------------------------------------------------------------------------

Step 3:

Create hello.jsp inside jsp folder of WEB-INF

WEB-INF/jsp/hello.jsp

Hello.jsp

-------------------------------------------------------------------------------------------------------------------------

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"

pageEncoding="ISO-8859-1"%>

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<html>

<head>

<title>Spring MVC </title>

</head>

<body>

${hello}

</body>

</html>

--------------------------------------------------------------------------------

$(hello) is used because in WelcomeController.java helloFunction()

Return object is ModelandView created with name of “hello”, because hello.jsp is present in WEB-INF/jsp folder .

Name of ModelandView same name of jsp should be present in jsp folder of web-inf

Other way is that instead of ModelandView we can redirect view from controller.

Step 4:

Create Web.xml inside WEB-INF folder

------------------------------------------------------------------------------------------

<?xml version="1.0" encoding="UTF-8"?>

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">

<display-name>Spring3MVC</display-name>

<welcome-file-list>

<welcome-file>index.jsp</welcome-file>

</welcome-file-list>

<servlet-name>spring</servlet-name>

<servlet-class>

org.springframework.web.servlet.DispatcherServlet

</servlet-class>

<load-on-startup>1</load-on-startup>

</servlet>

<servlet-mapping>

<servlet-name>spring</servlet-name>

<url-pattern>*.html</url-pattern>

</servlet-mapping>

</web-app>

-----------------------------------------------------------------------------------------

Above file showing servlet name is spring and mapping is *.html

So we are redirecting hello.html from index.jsp otherwise we can directly open

http://localhost:8081/springmvcapp/hello.html

Step 5: create spring-servlet.xml

In Web.xml dispatcher servlet name is spring so we need give web application context file name should be spring-servlet .xml (for more details Read MVC document from springsource.org)

Spring-servlet.xml will load by web server so need to add contextloadlistener into web.xml

To load Other spring xml files than spring-servlet.xml we need to add contextloadlistner and context param inside web.xml.

File Name : spring-servlet.xml

------------------------------------------------------------------------------------------

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xmlns:p="http://www.springframework.org/schema/p"

xmlns:context="http://www.springframework.org/schema/context"

xsi:schemaLocation="http://www.springframework.org/schema/beans

http://www.springframework.org/schema/beans/spring-beans-3.0.xsd

http://www.springframework.org/schema/context

http://www.springframework.org/schema/context/spring-context-3.0.xsd">

<context:component-scan

base-package="com.mahavirdhat.org.controller" />

<bean id="viewResolver"

class="org.springframework.web.servlet.view.UrlBasedViewResolver">

<property name="viewClass"

value="org.springframework.web.servlet.view.JstlView" />

</bean>

</beans>

------------------------------------------------------------------------------------------------------

Step 6:

Compile application using eclipse and create “springmvcapp.war” file using WAR export of eclipse

Copy springmvcapp.war file into deployment folder of JBOSS 7.1.1

C:\jboss-as-7.1.1.Final\standalone\deployments

You can start JBOSS server if it is not started already.

Step 7:

Go to browser and hit following url

http://localhost:8081/springmvcapp/index.jsp
