Creating and deploying a web application with Maven

Maven provides a convenient way to create and deploy web applications, using the "war" packaging type. Here's an example of how to create and deploy a simple web application using Maven:

• Create a new Maven project with the "webapp" archetype:

This will create a new Maven project with the directory structure and files needed to build a web application.

• Add any required dependencies to the project's POM file, using the <dependency> element. For example, to use the Spring framework in your web application, you would add the following to your POM file:

• Write your web application code, including any servlets, JSPs, and other web resources. Place your web resources in the "src/main/webapp" directory.

• Build the web application with the "war" packaging type:

This will build a WAR file for your web application, which will be located in the "target" directory.

• Deploy the web application to a web server, such as Apache Tomcat. To deploy the application, copy the WAR file to the "webapps" directory of the Tomcat installation, and start the Tomcat server. For example, if you are using Tomcat 9, you would copy the WAR file to:

• Access your web application by navigating to the appropriate URL in your web browser. For example, if your web application includes a servlet mapped to the "/hello" URL pattern, you would access it by navigating to:

This will invoke your servlet and display its output in your web browser.

Overall, Maven simplifies the process of creating and deploying web applications by providing a standardized project structure, build process, and dependency management system.
