How to fetch data from elasticsearch into java servlet?

Question

I'm making an application with react on the front end and java(dynamic web application with tomcat server) in the backend. I have some data stored in elasticsearch which I want to fetch into java and send them to react frontend. Got no ideas how to perform it. Any resources or some high level ideas will be greatly appreciated.

Thanks

I think you should use the following technology chain:

1. AJAX for making a rest call with JSON (browser)
2. JAX-RS for getting JSON requests (server)
3. Business service for getting data from elasticsearch (server)
4. JAX-RS for sending JSON response (server)
5. AJAX for receiving data (browser)
6. React for rendering received data (browser).
