My server details are as follows
Centos 6
apache 2.2.15

i am using static ip XX.XX.XX.XX

i have 4 interfaces configured in centos as follows

eth0 10.0.1.a
eth1 10.0.1.b
eth2 10.0.1.c
eth3 10.0.1.d

apache port 80 is listening on 10.0.1.a interface

i configured jboss port number 9393 in standalone.xml and started it and WAR file deployed.

But browser is not loading files and showing website.


My virtual host file is as follows

<VirtualHost *:80>

ServerName abc.com
ServerAlias www.abc.com

ErrorLog /var/log/httpd/abc-error.log
CustomLog /var/log/httpd/abc-access.log common env=!dontlog

RewriteEngine On
RewriteOptions Inherit

RewriteRule ^/$ /def/ [R=301,L]

ProxyRequests Off
ProxyPreserveHost On
<Proxy *>
Order deny,allow
Allow from all
</Proxy>

ProxyPass / http://localhost:9393/
ProxyPassReverse / http://localhost:9393/
<Location />

</VirtualHost>

What should be the cause?

Please explain what you mean by "not loading files and showing website". What you get in your browser when visiting http://www.abc.com?
From your post, my guess is that your app is running under the /def context in jboss. If that's the case, you should use:
Regards

website just loads and doesnt show anything. WAR file is not picking up resources.

I see an issue with your reverse proxy:

ProxyPass / http://localhost:9393/
ProxyPassReverse / http://localhost:9393/

ProxyPass is your source port while ProxyPassReverse should be the destination port you need traffic to move to. Let me show you what I mean....

If I have Apache Tomcat over SSL (port 8443) and I want it to be only accessible over HTTPS (port 443), I would add the following to my ssl.conf (in your case httpd.conf):

ProxyPreserveHost On
ProxyPass / http://localhost:8443/
ProxyPassReverse / https://localhost/
</VirtualHost>

That's all there is too it to run a reverse proxy. Try fixing those settings first (obviously change the information from my example) before trying anything else.

Did you try the config of my previous post?
If war "is not picking resources", then perhaps there is something wrong with application itself.
