Yes, the typical mechanism is to edit XML files. But there is the new Embedded Jopr project (http://www.jboss.org/embjopr) which provides an admin console. Embedded Jopr is part of AS 5.1.0.CR1, and you can download it for 4.2.3. In addition, you can download the Embedded Jopr 1.1 source code and build for 5.0.x.
Hi Peter thanks a lot for your information, it's seems a very helpfully console for Jboss. I'll be trying this console right now.
