Some http server and tomcat integration?

Question

JavaScript

Hello.
I can not understand for myself, can someone tell me?
I got the idea to experiment. But I still don't quite understand one thing.
I want to take a VPN, buy a domain name, try to install a server on it so that I can learn from real examples.
My difficulty is the following. Backend(REST) ​​- I develop in Java, respectively Maven -> war -> Tomcat.
I want to make Frontend as a separate project. Haven't decided yet either pure HTML+jQery or AngularJs - it doesn't matter.
But for Frontend I will need another server as I understand it. For example nginx or Apache HTTP.
Two servers, respectively 2 ports. And how to configure all this on 1 domain so as not to specifically specify the port?
I read about The Apache Tomcat Connector, off documentation and articles are https://www3.ntu.edu.sg/home/ehchua/programming/ho...
www.mydomen.com/index.html - the corresponding page from javaScript was opened ( Frontend) of the project. At the same time, it immediately requests the necessary information from the Backend project.
Then I need to submit a form from this page. Accordingly, POST to the Backend project that is running on Tomcat.
The essence of the question - how can I organize the correct operation of two projects on different servers and on the same domain name? Or what is the best way to organize this?
Thank you!

Answer 1

And what's the problem then? you raise tomkat on 8001 for example. On 80 nginx. And proxy everything that comes from /api/ to the tomcat. Give the nginx statics. A standard scheme for deploying web applications with Java backing.
Google for keywords tomcat nginx reverse proxy.

Answer 2

Let's say I set up this redirect and if I send the form from the frontend to the following address - (POST) www.mydomen.com/create, will nginx redirect this request to the tomcat server? For example, it will be on www.localhost:9000/, then the POST request will call www.localhost:9000/create?
I don't really understand this...
Thank you.
