Deploying a Web Application to an Embedded Jetty Server

Header Image

Ahoy there matey! Welcome aboard our quest to learn how to deploy a web application to an Embedded Jetty Server. Before we embark on this journey, let us first set sail by defining what Embedded Jetty is and why it’s a popular web server.

Introduction to Embedded Jetty

Embedded Jetty is a lightweight and fast web server that can be embedded in Java applications. It’s widely used in enterprise web applications due to its scalability and ease of use. Unlike traditional web servers, Embedded Jetty can be easily configured programmatically, making it an ideal choice for developers who want to customize the server to suit their specific needs.

How to deploy a web application to an Embedded Jetty Server, including using a WAR file

Deploying a web application to an Embedded Jetty Server is a breeze. There are two ways to deploy a web application: by using a WAR file or by configuring the server programmatically.

Deploying a web application using a WAR file

A WAR file (Web Application Archive) is a compressed file format used to package a web application’s files, including HTML, CSS, JavaScript, Java classes, and other resources. The following steps outline how to deploy a web application to an Embedded Jetty Server using a WAR file:

  1. Start by downloading and installing Embedded Jetty on your local machine. You can download the latest version of Embedded Jetty from the official website.

  2. Create a new directory in the Embedded Jetty server’s webapps directory and copy the WAR file into the new directory. For example, if you have a web application named “myapp,” create a directory named “myapp” in the webapps directory and copy the myapp.war file into it.

  3. Start the Embedded Jetty Server by running the main class of your application. Here’s some sample code to start an Embedded Jetty server:

Server server = new Server(8080);
WebAppContext webApp = new WebAppContext();
webApp.setContextPath("/myapp");
webApp.setWar("webapps/myapp/myapp.war");
server.setHandler(webApp);
server.start();
  1. Open your web browser and navigate to http://localhost:8080/myapp to access your web application. If everything was configured correctly, you should see your web application running smoothly.

Deploying a web application programmatically

In addition to using a WAR file, you can also deploy a web application programmatically. Here’s some sample code to deploy a web application programmatically:

Server server = new Server(8080);
WebAppContext webApp = new WebAppContext();
webApp.setContextPath("/myapp");
webApp.setResourceBase("src/main/webapp");
webApp.setDescriptor("src/main/webapp/WEB-INF/web.xml");
server.setHandler(webApp);
server.start();

In the code snippet above, we’re creating a new instance of the Embedded Jetty server and deploying a web application programmatically. We’re setting the context path to “/myapp” and configuring the server to look for the web application’s resources in the “src/main/webapp” directory. We’re also specifying the location of the web.xml file, which contains the web application’s configuration information.

Conclusion

Congratulations, ye landlubber! Ye have successfully learned how to deploy a web application to an Embedded Jetty Server, including using a WAR file. Now ye can set sail and explore the vast sea of web development using Embedded Jetty. Remember to keep practicing and experimenting to hone your skills. Fair winds and following seas, matey!
