Nginx as reverse proxy for Jetty

[Stefan Scott]

Hi -

I need some help configuring nginx as a proxy in front of Jetty (on
Debian).

Jetty is serving my Java web app correctly, because if I test it with
this lengthier alternate notation (which I also used before setting up
the nginx proxy), the Java web app login page appears and I can log in:

http://myhost.com:8080/testapp001.com


But when I do the following:

http://testapp001.com


I get the error message:

403 Forbidden
nginx/0.8.53



Here's my nginx.conf and testapp001.com.xml files

# This file is /etc/nginx/sites-available/testapp001.com
# Source: http://wiki.nginx.org/JavaServers

server {
  listen          80;
  server_name     .testapp001.com;
  access_log /var/log/www/testapp001.com/access.log;
  error_log /var/log/www/testapp001.com/error.log;

  root            /opt/jetty/webapps/testapp001.com;

  location / {
    index index.jsp;
  }

  location ~ \.do$ {
    proxy_pass              http://localhost:8080;
    proxy_set_header        X-Real-IP $remote_addr;
    proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header        Host $http_host;
  }
  location ~ \.jsp$ {
    proxy_pass              http://localhost:8080;
    proxy_set_header        X-Real-IP $remote_addr;
    proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header        Host $http_host;
  }
  location ^~/servlets/* {
    proxy_pass              http://localhost:8080;
    proxy_set_header        X-Real-IP $remote_addr;
    proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header        Host $http_host;
  }
}


The Java web app's WAR file has been decompressed to create this
directory:

/opt/jetty/webapps/testapp001.com


Here is file /opt/jetty/etc/testapp001.com.xml:

# Source: http://wiki.nginx.org/JavaServers

<?xml version="1.0"?>
<!DOCTYPE Configure PUBLIC "-//Mort Bay Consulting//DTD Configure//EN"
"http://jetty.mortbay.org/configure.dtd">
<Configure class="org.mortbay.jetty.webapp.WebAppContext">
  <Set name="configurationClasses">
     <Array type="java.lang.String">
       <Item>org.mortbay.jetty.webapp.WebInfConfiguration</Item>
       <Item>org.mortbay.jetty.plus.webapp.EnvConfiguration</Item>
       <Item>org.mortbay.jetty.plus.webapp.Configuration</Item>
       <Item>org.mortbay.jetty.webapp.JettyWebXmlConfiguration</Item>
       <Item>org.mortbay.jetty.webapp.TagLibConfiguration</Item>
     </Array>
  </Set>
  <Set name="contextPath">/</Set>
  <Set name="resourceBase"><SystemProperty name="jetty.home"
default="."/>/webapps/testapp001.com</Set>
  <Set name="virtualHosts">
   <Array type="java.lang.String">
      <Item>testapp001.com</Item>
    </Array>
  </Set>

</Configure>



This file is /opt/nginx/conf/nginx.conf - the correct symlink was also
created previously by doing:

sudo ln -s /etc/nginx/sites-available/testapp001.com
/etc/nginx/sites-enabled


worker_processes  1;

events {
    worker_connections  1024;
}

http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;
    include /etc/nginx/sites-enabled/*;
}


Here are last the 2 lines of the nginx log files:

#This is file /var/log/www/testapp001.com/access.log

host: "testapp001.com"

2010/11/18 19:17:32 [error] 13319#0: *3 open()

or directory), client: 999.999.999.999, server: testapp001.com, request:
"GET /favicon.ico HTTP/1.1", host: "testapp001.com"


(I have substituted "999.999.999.999" above instead of my client
machine's IP address. :-)

I have also tested setting the owner:group of directory

/opt/jetty/www/webapps/testapp001.com


three different ways:

cd /opt/jetty/www/webapps
sudo chown -R jetty:jetty testapp001.com
sudo chown -R root:root testapp001.com
sudo chown -R www-data:root testapp001.com


But navigating to 'http://testapp001.com' still gives the error message
"403 - Forbidden"

Navigating to 'http://myhost.com:8080/testapp001.com' correctly displays
the login page of the Java web app and lets me log in successfully - so
Jetty and the web app are working - I just can't get the nginx reverse
proxy configured properly.

Thanks for any help!
