How to Deploy Java Web Applications in AWS?

It can be a tad difficult to configure and manage all the servers when deploying the Java Web Applications on AWS. Using Java Web Applications, users can manage off-the-shelf and custom applications too. In this article, we’ll show you how to deploy your Java Web Application on AWS without hassle.

Why Use Java Web Application On AWS?

  1. AWS is built for application providers and vendors to secure their host applications seamlessly. Users can use web service APIs or management consoles to access the hosting platform. Hence, AWS is fairly easy to use and, with the right resources, not difficult to learn.
  1. It is highly cost-effective as users only have to pay for the storage and the computing power. There are no long-term contracts, shady third-party deals or any other unnecessary commitments. Users can compare the costs of various AWS services online and choose one that suits them best according to their needs and interests.
  1. AWS is highly scalable, and users can either scale it up during high demand or scale it down as demand dwindles to save costs. Since Amazon’s infrastructure backs it, users can access various storage resources when needed.
  1.  It is flexible enough for users to choose the programming language or the operating system, including the database. AWS provides a virtual platform for users to load the services or the software that the application needs to facilitate the migration process for the already existing applications while taking the initiative to build new ones.
  1.  One of the best advantages is the security, again, owing to the infrastructure backed by Amazon. AWS takes every means necessary to secure the whole infrastructure, including various software measures.

Deploying Java Web Applications In AWS

There are a few things that you must keep in mind before deploying Java web applications in AWS.

  • Understand the various deployment processes, including the various installation and configuration statistics.
  • Try to use automation whenever possible and prioritise tasks in areas where consistency is important.
  • Always protect your application by leveraging source codes or using application repositories.
  • Always keep realistic expectations when working with the application. Initial deployment and scaling may not always go according to plan.

With that being said, take a look at the various steps to deploy a Java Web application in AWS.

  1. First, you need to create a simple Java web application. You can create it in Eclipse. Follow this path File> New> Dynamic Web Project, and give the project a name. Click Next and then Finish, and you’ll find out that you have created a project in the workspace.
  1.  For the next step, we will use JSP, so right-click on the DemoWebApp> New> JSP file and name the file. After that, you can write some random text in the JSP file.
  1. Before deploying to the AWS, you’ll need to check this application locally to reduce the chances of errors or setbacks during deployment. Use the command prompt to navigate the Tomcat directory.
  1. Start the Tomcat, head over to your project in Eclipse, select properties by right-clicking on it, go to Server and choose Tomcat server. Finally, click apply and then close it.
  1. You need to run your project as Run on Server by right-clicking on it, and if it works, then you’ll see the sample text that you wrote. Thus, we have successfully tested our application locally. Now choose the WAR file from the Exports by right-clicking on the project. You can enter the path where you want to save the WAR file.
  1. Next, we’ll have to deploy the application on AWS. Select Elastic Beanstalk from the AWS homepage Services menu. Please create a new application, name it and create a new environment. Upload the WAR file in the Application Code after selecting Tomcat in the preconfigured platform.
  1. After the upload is complete, you can see the WAR file along with the URL.


In a few clicks, your Java web application is ready to be deployed in AWS. We hope that by reading this article, you have understood how to do it.
