Making non-server specific EAR

[JC Bustamante]

I am currently working on a project that uses an MDB to read messages off of an MQ queue, process them, and then write the response to another queue on the same queue manager.

The issue that we are having is that we have server specific data such as the hostname, queue name to drain from etc. within our ejb-jar.xml. This is a hastle for our build team because they require a new EAR file for each JBoss server they deploy the application on. My question is the following. Is there a way to separate the server specific data from the ejb-jar.xml?

The technologies that we use are IBM Websphere MQ Explorer with fixpack 6.0.2, JBoss AS 4.0.5.GA, java 1.5_011.

The following is a sample EJB definition from our ejb-jar.xml.

   <ejb-name>Listener1</ejb-name>

    <!-- to send the response. -->
