How To Install Java Application From Plesk?
Introduction
JavaServer Pages (.jsp) files are not directly accessible on a Windows Plesk server like .php files. To execute a Java application, one has to compile it into a .war (Web Application ARchive) file and afterwards deploy the file on the server. Plesk also offers a simple method of uploading and deploying a .war file through the control panel.
What is a .WAR File?
A .war file is a compressed format used to package a complete web application that runs on a Java application server. It contains all the components required, including .jsp pages, servlets, class files, and other required resources, so that by deploying a single file, the server to correctly run your entire Java-based website.

In this section, you will be guided on the simple steps you will have to follow in the Plesk panel to upload and execute your Java web application.
Log In and Select Domain
To start with, you need to log in to your Plesk. Click on the Domains section and get the list of domains hosted, and then choose the domain in which you wish to deploy the Java application.
Go to Web Applications
On the dashboard of the domain, locate the Application and Services section and access the Web Applications option. This is the page where you can manage different types of web applications.
