What is a WAR file, and what does it do?

On a shared hosting environment for Tomcat, you can deploy your WAR file using the following methods:

1. Tomcat WAR file deploying using Tomcat Manager

Deploying a WAR file via Tomcat Manager is fast and most effective when deploying WAR files to Tomcat.

With this option, you can upload your WAR file directly through Tomcat Manager and deploy it to the server.

2. Tomcat deploy WAR file using FTP

Upload your WAR file to your web hosting server using an FTP client like FileZilla.

When deploying war file in Tomcat, if you want your application to be available at the root "/" context, ensure you name the WAR file ROOT.war

If Tomcat doesn't automatically deploy the WAR file, you can restart Tomcat through your control panel so that it deploys the WAR file.
