The difference between Web engineering and Java Engineering

1. Do I need request and response?

If you need request and response, it's web engineering. If you don't need it, it's Java engineering.

Web Engineering requires a shell, middleware (Tomcat). and the request and response is what Tomcat helped us instantiate, and Tomcat assembled the page data into a request and we returned it to Tomcat via response.

2. The difference between a war package and a jar package

A war package is a Web project, and a jar package is a Java project.

War packages and jar packages are engineered, and jar packages are for war engineering. The jar cannot run independently, and the war package can run independently.
