Nginx Jboss

Hello,

I just configured a reverse proxy (latest version), but i have a problem let me explain:
I have a Firewall with one interface DMZ and a server reverse proxy with two interfaces
First interface : (DMZ) : Subnet 172.16.0.10/24
Second interface ( LAN) : Subnet 192.168.55.253/24
and i have a web frontal web : 192.168.55.177

my objective : all requests on my DMZ interface (http://172.16.0.10) have to be redirected on the frontal web server throught the LAN interface
But my problem is that i have an "404 not found"
My web application is Jboss 7 and my URL is : http://X.X.X.X/virtuoso/XXXX
In attachment my configuration file

Do you have an idea?
Nginx is compatible with Jboss application?

Best Regard
