Maven Web Application: Creating web application in Maven 3

Advertisement
Learn to develop Maven based Web Application using maven build tool. In this tutorial you will learn how to create web application in Maven 3.

How to create Maven based Web Application? You will learn to create web application using maven archetype. We are using the Maven 3 build tool.

In this tutorial I will explain you the process and command of creating a web application using Maven 3 project management tool. You will also learn how to run it on the Tomcat Server. We will create the war file using

I am assuming you are aware of web applications and you have experience in the development of web applications. Here we will create a web application using Maven archetype.

Let's Start developing the application.

Step 1: Create sample web application using Maven archetype

Now we will tell you about the maven archetype for creating the web application. The maven-archetype-webapp is used to create web application using maven tool. Here is the syntax of the command:

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

You can replace the package and the project-name values and then create the project.

Here is the video instruction of creating web application in Mave:

Here is simple example of creating web application:

mvn archetype:generate -DgroupId=net.roseindia -DartifactId=myfirstwebapp -DarchetypeArtifactId=maven-archetype-webapp -DinteractiveMode=false

Here is the output of the command:

C:\Users\user>d:

D:\>mkdir mavenexamples

D:\>cd mavenexamples

D:\mavenexamples>mvn archetype:generate -DgroupId=net.roseindia -DartifactId=myfirstwebapp -DarchetypeArtifactId=maven-archetype-webapp -DinteractiveMode=false

D:\mavenexamples>

Step 2: Understanding Maven directory structure.

The above command will create a web application. Here is the directory structure of the web application:

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

Step 3: The maven pom.xml file

The maven pom.xml file contains the information about project and its dependencies. Here is the code of the pom.xml file:

<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>net.roseindia</groupId>
  <artifactId>myfirstwebapp</artifactId>
  <packaging>war</packaging>
  <version>1.0-SNAPSHOT</version>
  <name>myfirstwebapp 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>myfirstwebapp</finalName>
  </build>
</project>

Step 4: Code of the web.xml file

Here is the code of the web.xml file:

<!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>

Step 5: Code of index.jsp file.

Here is the code of the index.jsp file:

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

The index.jsp file simply displays the "Hello World!" message on browser.

Step 6: Building war file

First of go to the directory "myfirstwebapp". To create a war file you just have to type following command on the console:

mvn package

Here is the output of the program:

D:\mavenexamples\myfirstwebapp>mvn package
[INFO] Scanning for projects...
[INFO]

[INFO] ------------------------------------------------------------------------
[INFO] Total time: 2.421s
[INFO] Finished at: Tue Jan 14 12:09:53 IST 2014
[INFO] Final Memory: 5M/15M
[INFO] ------------------------------------------------------------------------
D:\mavenexamples\myfirstwebapp>

Step 7: Deploying application

Copy the war file into webapps directory of your Tomcat server and start the Tomcat. Type http://localhost:8080/myfirstwebapp in your browser. The "Hello World!" message should be displayed in the brower.
