How to make a web page like in the logs?

Question

JavaScript

Hello, I work with servlets, I have such a problem: I can’t display information on the page as in logs (ready-made information is simply added to the end). For example: I have a page I refer to servlets, and it outputs something to a simple class and refers to another class, and it outputs something else at the end of the page, well, like this. How to implement this please help, I really need it, I tried it through ajax, but I couldn't... Thank you.

What you described is theoretically implemented using a persistent connection. It can also be implemented using web sockets. The question is the practical application of all this.
