Why is the server not receiving anything?

Question

JavaScript

I’m trying to apply, study AJAX, but a problem immediately arose - the field value does not come to the server, and in general the GET request in the browser field looks like this: localhost:8080/?myInput=hello , I don’t understand why my servlet is not registered, and, accordingly, not I can catch this variable on the server and output it to the console.
Can you please tell me where is the bug?

Answer 1

so on the second screen what URL did you do? use myInput there ,
and in the controller (screen 3) wait for GET inputValue
