Question

Answer 1

Create servlet which will handle get/post requests, invoke your java code and return result.

Answer 2

This cannot be done using simple html pages. You should be using JSP files instead which will let you make a call to your JAVA classes methods through directives.

This is common guess since you did not provide much relevant information about your project structure.

Answer 3

You have to use JSP. Here is a simple tutorial that could be useful to start. JSP tutorial

Good luck!

Answer 4

You should work with frameworks. I recommend you SPRING MVC. It`s very good and easy to use. For calling a java class you need jQuery and the framework.
