How to create a Web Application Project with Maven

In this tutorial, we will show you how to use Maven to create a Java web application (with Spring MVC) project, and make it support Eclipse IDE.

Tools used :

Maven 3.0.5
Eclipse 4.2
JDK 6
Spring 3.2.0.RELEASED
Tomcat 7

1. Web Application Project from Maven Template

In a terminal (*uix or Mac) or command prompt (Windows), navigate to the folder you want to store the project. Issue following command :

mvn archetype:generate -DgroupId={project-packaging} -DartifactId={project-name} -DarchetypeArtifactId=maven-archetype-webapp -DinteractiveMode=false

This tell Maven to create a Java web application project from “maven-archetype-webapp” template.

For example,

$ pwd
/Users/mkyong/Documents/workspace
 
$ mvn archetype:generate -DgroupId=com.mkyong -DartifactId=CounterWebApp -DarchetypeArtifactId=maven-archetype-webapp -DinteractiveMode=false

[INFO] Finished at: Thu Dec 20 20:35:19 MYT 2012
[INFO] Final Memory: 12M/128M
[INFO] ------------------------------------------------------------------------

In above case, a new web application project named “CounterWebApp“, and the entire project directory structure is created automatically.

2. Maven Directory Layout

Maven created following web application directory layout. A standard deployment descriptor web.xml and Maven pom.xml are created.

CounterWebApp
   |-src
   |---main
   |-----resources
   |-----webapp
   |-------index.jsp
   |-------WEB-INF
   |---------web.xml
   |-pom.xml

Note
Please check this official guide to understand more.

pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" 
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  	xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 
	http://maven.apache.org/maven-v4_0_0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <groupId>com.mkyong</groupId>
  <artifactId>CounterWebApp</artifactId>
  <packaging>war</packaging>
  <version>1.0-SNAPSHOT</version>
  <name>CounterWebApp Maven Webapp</name>
  <url>http://maven.apache.org</url>
  <dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>3.8.1</version>
      <scope>test</scope>
    </dependency>
  </dependencies>
  <build>
    <finalName>CounterWebApp</finalName>
  </build>
</project>

web.xml – Servlet 2.3 is too old, consider upgrade to 2.5

<!DOCTYPE web-app PUBLIC
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" >
 
<web-app>
  <display-name>Archetype Created Web Application</display-name>
</web-app>

index.jsp – A simple hello world html file

<html>
<body>
<h2>Hello World!</h2>
</body>
</html>

3. Eclipse IDE Support

To convert the Maven web project to support Eclipse IDE, in terminal, navigate to “CounterWebAPp” folder, issue this command :

mvn eclipse:eclipse -Dwtpversion=2.0

You must add the -Dwtpversion=2.0 argument to make it as a Eclipse web project. Imports it into Eclipse IDE, a globe icon on top of project, means this is a web project in Eclipse.

You want Eclipse web project NOT Eclipse Java project.
Many users are confused, again, if you just issue mvn eclipse:eclipse, it will only convert the project as Eclipse Java project, add extra -Dwtpversion=2.0 argument to make it as Eclipse web project.

Done. This web project is ready to deploy. Attached to Eclipse’s Tomcat server plugin, and start it.

You can access the hello world jsp via – http://localhost:8080/CounterWebApp/

4. Update POM

To make above Maven web project to support Spring MVC framework, we need to touch up on the existing pom.xml :

Add compiler plugin to specify JDK6 to compile this project (default is using JDK1.4).
Add Spring frameworks dependencies.
Update jUnit to latest 4.11.

pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" 
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 
	http://maven.apache.org/maven-v4_0_0.xsd">

					<target>${jdk.version}</target>
				</configuration>
			</plugin>
		</plugins>
	</build>
</project>

5. Spring MVC REST

Create a Spring MVC controller class, with two simple methods to print a message.

/src/main/java/com/mkyong/controller/BaseController.java

package com.mkyong.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("/")
public class BaseController {
 
	@RequestMapping(value="/welcome", method = RequestMethod.GET)
	public String welcome(ModelMap model) {
 
		model.addAttribute("message", "Maven Web Project + Spring 3 MVC - welcome()");
 
		//Spring uses InternalResourceViewResolver and return back index.jsp
		return "index";
 
	}
 
	@RequestMapping(value="/welcome/{name}", method = RequestMethod.GET)
	public String welcomeName(@PathVariable String name, ModelMap model) {
 
		model.addAttribute("message", "Maven Web Project + Spring 3 MVC - " + name);
		return "index";
 
	}
 
}

Create a Spring configuration file, defines the Spring view resolver.

/src/main/webapp/WEB-INF/mvc-dispatcher-servlet.xml

<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	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.mkyong.controller" />
 
	<bean
		class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<property name="prefix">
			<value>/WEB-INF/pages/</value>
		</property>
		<property name="suffix">
			<value>.jsp</value>
		</property>
	</bean>
 
</beans>

Update existing web.xml to support Servlet 2.5 (the default Servlet 2.3 is too old), and also integrates Spring framework into this web application project via Spring’s listener ContextLoaderListener.

/src/main/webapp/WEB-INF/web.xml

<web-app xmlns="http://java.sun.com/xml/ns/javaee"
	      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	      xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
	      http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
	      version="2.5">	
 
	<display-name>Counter Web Application</display-name>
 
	<servlet>
		<servlet-name>mvc-dispatcher</servlet-name>
		<servlet-class>
			org.springframework.web.servlet.DispatcherServlet
		</servlet-class>
		<load-on-startup>1</load-on-startup>
	</servlet>
 
	<servlet-mapping>
		<servlet-name>mvc-dispatcher</servlet-name>
		<url-pattern>/</url-pattern>
	</servlet-mapping>
 
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>/WEB-INF/mvc-dispatcher-servlet.xml</param-value>
	</context-param>
 
	<listener>
		<listener-class>
			org.springframework.web.context.ContextLoaderListener
		</listener-class>
	</listener>
</web-app>

Move existing index.jsp inside folder WEB-INF, to protect user access it directly. In additional, edit the file to print out the ${message} variable that pass by the controller.

/src/main/webapp/WEB-INF/pages/index.jsp

<html>
<body>
<h2>Hello World!</h2>
 
<h4>Message : ${message}</h1>	
</body>
</html>

Review the final directory structure

6. Eclipse + Tomcat

In order to start or debug this project via Eclipse server plugin (Tomcat or other container). You need to issue following command again, in order to make all dependencies attached to the project web deployment assembly.

mvn eclipse:eclipse -Dwtpversion=2.0

Before this command, project dependencies are empty.

After this command, now project dependdencies are here!

Important!
Many developers are trapped here, and failed to perform the starting or debugging in Eclipse server plugin, all failed by showing dependencies not found error message. Right click on your project properties, make sure all dependencies are inside the web deployment assembly, otherwise issue mvn eclipse:eclipse -Dwtpversion=2.0 again!

7. Maven Packaging

Review the pom.xml again, the packaging tag defining what is the packaging format or output.

pom.xml

<project ...>
	<modelVersion>4.0.0</modelVersion>
	<groupId>com.mkyong</groupId>
	<artifactId>CounterWebApp</artifactId>
 
	<packaging>war</packaging>
	<version>1.0-SNAPSHOT</version>

Package the project to deploy is easy, just issue mvn package, it compiles and package the web project into a “war” file and store in project/target folder.

For example :

$pwd
/Users/mkyong/Documents/workspace/CounterWebApp
 
Yongs-MacBook-Air:CounterWebApp mkyong$ mvn package
[INFO] Scanning for projects...
[INFO]                                                                         
[INFO] ------------------------------------------------------------------------

[INFO] Finished at: Thu Dec 20 22:28:53 MYT 2012
[INFO] Final Memory: 14M/206M

Done, just copy the project/target/CounterWebApp.war file and deploy to your container.

Everything was working until the last part of the tutorial. I tried to access http://localhost:8080/CounterWebApp/welcome/mkyong
Then i got :
HTTP Status 500 – Request processing failed; nested exception is org.springframework.web.bind.annotation.support.HandlerMethodInvocationException: Failed to invoke handler method [public java.lang.String com.mkyong.controller.BaseController.welcomeName(java.lang.String,org.springframework.ui.ModelMap)]; nested exception is java.lang.IllegalStateException: No parameter name specified for argument of type [java.lang.String], and no parameter name information found in class file either.

  Strange, i was able to access http://localhost:8080/CounterWebApp/welcome/mkyong after rebooting my laptop the next day.
Anubhab May 14, 2013 at 3:01 pm
Hi Can you tell me how can you access the war version name in index.jsp??
Suppose the war i create is like appName-1.1.2.war.
I want to print the version i.e. “1.1.2″ in my index.jsp.
How is that possible?
Dino May 13, 2013 at 12:38 pm
The tutorial is awesome, it saves me lots of time on troubleshooting. Thank you so much.
BTW, I encountered error of “Java compiler level does not match the version of the installed Java project facet” when I tried the step 1 for the first time. I was still able to run the project, but had a red cross on the project. The solution can be found here, http://stackoverflow.com/questions/7715260/java-compiler-level-does-not-match-the-version-of-the-installed-java-project-fac
I am using Maven 3.0.5, jdk 1.7.0_10, Eclipse Java EE Juno. But later I was not able to reproduce it.

Hi ,
Can you let me know how to import a web project in eclipse ?I am not able to do it.
Regards
Chinmay

  Hello,
  if you want to import other project into eclipse just Right click on your project explorer and select import –> General—->Existing Projects into workspace, in this window you need to browse for the actual path where your project has to imported
Pierluigi March 20, 2013 at 8:06 pm
you are a cool guy MK, your tutorial really helped me getting started with Maven… all this XML is a nightmare anyway. I am looking for alternatives because all that XML visual noise drives me crazy.
Maulana March 18, 2013 at 5:50 pm
Hello,
I’m a newbie for eclipse and java. my background was Delphi and VB. now I’m learning java and eclipse. it is quite interesting to build web application using maven. but what if I want to create java project using maven, what archetype should I use, while in eclipse when I choose the maven project a lot of maven archetype can we select, and what if I separate the front end project (web application) and back end project (i.e for connecting to database) what should I do then.
thank you
Sarath March 15, 2013 at 1:35 am

Hello sir, how can I create a Maven Java Application with Netbeans ?

Leo January 23, 2013 at 6:55 am

For convenience, we can declare maven-eclipse-plugin in file pom.xml to avoid typing the parameter “-Dwtpversion=2.0″ when use command mvn eclipse:eclipse.

mkyong January 23, 2013 at 9:21 am
Thanks for your invaluable input :)

Dave Potts January 12, 2013 at 7:51 pm
I tried this, when I tried to import it into Eclipse, eclipse bailed out with an internal error.
I then attempted to repeat the procedure from within eclipse, following the instructions from https://docs.sonatype.org/display/M2ECLIPSE/WTP+mini+howto, which is the offical support site for the maven plugin used in this demo.
[Also includes instructions on how to create a java source folder]
Result Eclipse did not die and I can correctly configured eclipse/maven web project.
Igor December 31, 2012 at 3:41 pm
Hi MK,
maven-archetype-webapp creates directory structure without standard src/main/java folder. In this tutorial i can’t find part where src/main/resources is renamed to src/main/java.
Thanks,
Igor
- mkyong January 1, 2013 at 8:27 am
  Create the folder structure manually :)
- kasi May 3, 2013 at 10:56 am
  this should be done, else the target has the java file not the class files. In ‘basecontroller’ also import import org.springframework.web.bind.annotation.PathVariable;
  for a new bee every thing should be same else we need to spend hours in making the project work.
  thanks for your work, mkyong
yasser December 21, 2012 at 8:17 pm
thank you very much very nice and usful lesson .i bookmark this site ,i love it coz i want learn programming .. thanks alot

dli7mar November 18, 2012 at 11:31 pm

Hi mkyong,

I have a maven3/jpa2/tomcat7/eclipse project, which has these jpa related dependencies in its pom.xml:

&lt;dependency&gt;
        	&lt;groupId&gt;org.hibernate&lt;/groupId&gt;
        	&lt;artifactId&gt;hibernate-entitymanager&lt;/artifactId&gt;
        	&lt;version&gt;3.6.5.Final&lt;/version&gt;
        	&lt;scope&gt;provided&lt;/scope&gt;
        &lt;/dependency&gt;
        &lt;dependency&gt;
    		&lt;groupId&gt;org.hibernate.javax.persistence&lt;/groupId&gt;
    		&lt;artifactId&gt;hibernate-jpa-2.0-api&lt;/artifactId&gt;
    		&lt;version&gt;1.0.0.Final&lt;/version&gt;
	&lt;/dependency&gt;      
	&lt;dependency&gt;
		&lt;groupId&gt;org.hibernate&lt;/groupId&gt;
		&lt;artifactId&gt;hibernate-core&lt;/artifactId&gt;
		&lt;version&gt;3.6.7.Final&lt;/version&gt;
	&lt;/dependency&gt;

After running ‘mvn eclipse:eclipse’ command, I could see hiberante-entitymanager-3.6.5.Final.jar in the project. But after running ‘mvn package’ commeand, this jar file did not go $my_project\target\my_project\WEB-INF\lib fold. When I deply the war file to tomcat, I need to manually copy/paste this jar file to tomcat to run it.

Do you know why this issue happened? Any idea is greatly appreciated.
Thank you so much.

Delete the “scope” tag, “provided” means your container will provide this jar, so it will not package into the war file.

        &lt;dependency&gt;
        	&lt;groupId&gt;org.hibernate&lt;/groupId&gt;
        	&lt;artifactId&gt;hibernate-entitymanager&lt;/artifactId&gt;
        	&lt;version&gt;3.6.5.Final&lt;/version&gt;
        &lt;/dependency&gt;

Hi, will you please explain the details of running in tomcat?
>In Eclipse, create a server instance, add above “primefaces” web project and start it.

  Just tested the command again, and the web.xml is created successful. May be you can try the command again, or send me your command.

  The command is right. But you need to remove the invisible NL char between the second and first line.

using the -DgroupId=com.store.controllers here.. was needless since it didn’t create the package although the webApp was successfully created.
mvn archetype:generate -DgroupId=com.store.controllers -DartifactId=shoppersStop -DarchetypeArtifactId=maven-archetype-webapp -DinteractiveMode=false
I would say .. that the project folder structure was partially created ..
well but at least I am happy that I am learning maven no matter if in parts.. haha..
But thanks .. mkyong!!! you are the best when it comes to practising technologies.

  Agreed with you, Maven should generate the packaging folder as well.
