How to set substitution values?

[g.tomassoni]

I have a question which is probably a "newby" one.

When I develop some EAR, I'm used to assign some of the properties and attributes through substitution macros (in example: ${it.site.root} in the <context-root> of a module in the application.xml).

This lets me change some values depending whether I am deploying it on a staging or on a production server, in example.

I'm used to define the values of these macros among the runtime options I specify to start jboss. Unfortunately, this seems suboptimal to me, because:

- I need to modify the jboss startup script to do this;
- I need to restart JBoss in order to change these macros;
- I can't simply deploy the same app with two different names to have two different instances.

Is there any better way to do this? I tried to discover a way by meself, browsing the docs, but I don't think I found anything of useful.

Thanks,

You can set these properties using this:
http://www.redhat.com/docs/manuals/jboss/jboss-eap-4.2/doc/Server_Configuration_Guide/Additional_Services-System_Properties_Management.html

Your properties can be changed from the JMX console or in the file, if you have access to it.

Once set, you can then restart your .ear file by touching it or if exploded, the application.xml file.

To deploy the same .war file with a different context ... I'm not sure if this is allowed or not. You could have ${it.site.root2} or something ....

Great! Thank you, Elias.

I guess this is not possible, since the service you suggested seems to apply AS-wide. Anyway, that's a great start to me. Thank you again.
