What is WAR file?

Files with WAR file extensions are associated with the Java Web Archives. WAR files are compressed packages, including Java-based web components and applications run on a server.

They are essential for storing server-side utility classes, static web resources, and client-side classes. Also, the WAR file includes a Web deployment descriptor file, an XML file containing deployment information, MIME types, session configuration details, and other needed settings.
