So, in essence, Apache is an HTTP server that serves HTTP requests. Tomcat is a Java Servlet and JSP server that provides support for Java technologies.

 

What exactly is the difference between war and jar?

Web Application Archive files (.war files) run within a programme server, while Java Application Archives (.jar files) run on the user’s computer and are used to execute a desktop application (.jar files). It is possible to package web applications with the help of a particular jar file, which can then be deployed on an application server with relative ease using a war file.

 

What exactly is the content of the WAR file?

The following resources are often found in a WAR: Servlets, JavaServer Pages (JSP), and Custom Tag Libraries are all examples of server-side programming. Utility classes on the server side (database beans, shopping carts, and so on). Web resources that are not dynamic (HTML, image, and sound files, and so on).

 

What is the process of creating war files?
