This is really a "IBM Websphere MQ" question, since those activation properties come from that application. There are a couple ways to solve this. One you can use Java system property, e.g. mq.host, and define this using -D, and then have the XML text be ${mq.host} for the host name property. This is probably the easiest. The other is to extend the inflow adapter class: http://www.jboss.org/wiki/Wiki.jsp?page=ConfigJMSMessageListener See: JBossJMSMessageEndpointFactory.augmentActivationConfigProperties View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4095438#...
