Help needed with WebSphere MQ JCA configuration

jimjoyce Oct 15, 2007 4:19 PM

I have been through the Wiki guide to configuring the WebSphere MQ as documented here: http://wiki.jboss.org/wiki/Wiki.jsp?page=UsingWebSphereMQSeriesWithJBossASPart4

While I can get it working using the instructions verbatim, I would prefer to configure some of the connection information externally (i.e. not in the ebj-jar.xml file OR the jboss.xml file). Ideally, this would be in a single resource file where the rar file is introduced.

This would enable me to produce a single artifact and deploy it to development, test and production tiers without the need to rebuild the ear file.

MQ series is required, so don't ask if JBossMQ may be substituted. The project leader simply wants to move a Messaging application from WAS.

Thanks in advance for your consideration.

To configure the WASMQ activation spec an ejb-jar.xml/jboss.xml file is required. There is no external means to do this with the WSMQ rar as it is per EJB (listener) deployment. A certain amount of configuration information for the destinations is available in the admin objects themselves, but for a listener deployment the above mechanism is really the only route.

Actually, in furthering this thread

http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4095438#4095438

You could set it up to reference system properties or properties replacement in your ejb-jar.xml file. JBoss provides a properties-service.xml file that can be used to set properties dynamically. So, in your ejb-jar.xml file you could set properties for your WASMQ specific information and keep that information in the properties-service.xml file or set then in your run.sh/bat script,.

More can be found here:

http://wiki.jboss.org/wiki/Wiki.jsp?page=SystemPropertiesInConfigFiles

and here

http://wiki.jboss.org/wiki/Wiki.jsp?page=PropertiesService

This would at least enable you to externalize this info into one place which from your original post I believe is what you want.

Thanks to genman for this. I had completely forgotten about the dynamic replacement for properties on the host.
