To create a simple java web application, we will use maven-archetype-webapp plugin. So, let’s open the command console, go to the C:\MVN directory and execute the subsequent mvn command.
C:\MVN>mvn archetype:generate
-DgroupId = com.companyname.automobile
-DartifactId = trucks
-DarchetypeArtifactId = maven-archetype-webapp
-DinteractiveMode = false
Maven will start ongoinging and will create the complete web based java application project structure as follows −

Now go to C:/MVN directory. You’ll see a java application project created, named trucks (as specified in artifactId) as specified in the subsequent snapshot. The subsequent directory structure is generally employed for web applications −

Maven uses a standard directory layout. Using the above example, we can understand the subsequent key concepts −

Sr.No.	Folder Structure & Description
1	trucks contains src folder and pom.xml.
2	src/main/webapp contains index.jsp and WEB-INF folder.
3	src/main/webapp/WEB-INF contains web.xml
4	src/main/resources it contains images/properties files.

POM.xml

If you observe, you will find that Maven also created a sample JSP Source file.
Open C:\ > MVN > trucks > src > main > webapp > folder to see index.jsp with the subsequent code −
<html>
<body>
<h2>Hello World!</h2>
</body>
</html>

Build Web Application

Let’s open the command console, go to the C:\MVN\trucks directory and execute the subsequent mvn command.
C:\MVN\trucks>mvn clean package
Maven will start building the project.

Deploy Web Application

Now copy the trucks.war created in C:\ > MVN > trucks > target > folder to your webserver webapp directory and restart the webserver.

Test Web Application

Run the web-application using URL: http://<server-name>:<port-number>/trucks/index.jsp.
Verify the output.
