How to set up nginx server to proxy to a java application

I have a nginx server sitting on dmz to poing traffic to a java application.  The reason why i call it java application is because it only has a xxx.jar file running. I could like to proxy the http traffic to the java application. The port is poart 80. I did the following nginx configuration as below, but it doesn't work. Is there any nginx experts here can help me with this issue?


[root@pmsdev jyu]# ps -ef | grep java
root      3108     1  0 13:29 ?        00:01:56 java -Dspring.profiles.active=dev -jar /data/AveryRollProduction.jar /tmp
root      3933  3918  0 17:24 pts/0    00:00:00 grep --color=auto java

    server {
        listen       80 default_server;
        listen       [::]:80 default_server;
        # server_name  localhost;
        # root         /usr/share/nginx/html;

        server_name  localhost;
        root         /usr/share/nginx/html;

        # Load configuration files for the default server block.
        include /etc/nginx/default.d/*.conf;

        location / {

        proxy_set_header X-Forwarded-Host $host;
        proxy_set_header X-Forwarded-Server $host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_pass http://10.104.0.104:80;
