I have a VPS server with Ubuntu 18 O.S. In this VPS I have installed VESTA CP, which comes with Apache 2 and Nginx. After that I have intalled Tomcat 9(port 8082) to serve a Java Spring based webapp.
If I enter the address "serverIP:8082/AppFolder" I can access the app, but I want to redirect the apache server to the tomcat one, so I can write the domain name and load the webapp.

I have tried .htaccess file but it shows an apache error page. I have no permission to view this file is the message.

What can I do to solve this?

-Nginx config:

location / gz

location /error/ 
 alias /home/admin/web/webapp.com/document_errors/;


location @fallback 
 proxy_pass http://IP:8080;

-Apache config:

<VirtualHost IP:8080>

 ServerName webapp.com
 ServerAlias www.webapp.com
 ServerAdmin info@webapp.com
 DocumentRoot /home/admin/web/webapp.com/public_html 
 ScriptAlias /cgi-bin/ /home/admin/web/webapp.com/cgi-bin/
 Alias /vstats/ /home/admin/web/webapp.com/stats/

Thanks.

Finally I have found an answer...editing the config file of nginx:

proxy_pass http://IP:8082; <--TOMCAT PORT
root /home/admin/web/webapp.com/public_html; <--JSP PAGES PATH

Default config file has the Apache port and apache html pages path.
I suppose this can be done using apache proxy_mod, but I don´t know which way is better...if anyone can explain the two ways(via apache or via nginx) I apreciate it.
