Answer 1

1 approach:-

in jquery api, to call any backend system , in your case java, you need to do ajax call to invoke your java controller or service.

jquery ajax post call (call your java controller here)

2nd approach:-

if you need java class to take part in your jsp formation , you can go for custom tags, in your case you can look for jsf framework which basically bind your user events to your controller.

other frameworks - springmvc bind your jsp attributes to its corresponding models, in this case no need to use jquery , you can achieve it through spring custom tags.
