Hi !
This is my understanding,
A jar file is a java archive file, which bundles java classes(utility) with some static files like images or videos for easy accessibility.

A war file is a web application archive which bundles JSP/Servlet classes, html, images and videos.

My question is, can jar have only java classes and not JSP files or html files. But war file can also have jsp files and html files, is that the prime difference between jar and war files.

Thanks
AJP
