I have configured virtual host in JBoss 6.x EAP. Configuration of web subsystem is as follows:

<subsystem xmlns="urn:jboss:domain:web:2.2" default-virtual-server="virtualServer1" native="false">

      <connector name="http" protocol="HTTP/1.1" scheme="http" socket-binding="http"/>

     <connector name="ajp" protocol="AJP/1.3" scheme="http" socket-binding="ajp"/>

     <connector name="myhttp" protocol="HTTP/1.1" scheme="http" socket-binding="myhttp"/>

     <virtual-server name="default-host" enable-welcome-root="true">

          <alias name="localhost"/>

          <alias name="example.com"/>

     </virtual-server>

     <virtual-server name="virtualServer1" enable-welcome-root="true">

          <alias name="A.technologic.com"/>

     </virtual-server>

     <virtual-server name="virtualServerA" enable-welcome-root="true">

          <alias name="B.technologic.com"/>

     </virtual-server>

</subsystem>

I also maintain a properties file in my application, where I mention alias name, http/https port and my application context name.

My application is deployed with and without jboss-web.xml. Since I also maintain a property file in my application which stores the said properties, Is "jboss-web.xml" required? If yes, why?
