Using the DeploymentService seems to be working. What I did was to convert my Service Archive to interface with the DeploymentService and added in the undeploy and deploy methodology. This allows the admin the ability to change the Service Archive params on the fly to reconfigure the DataSource. The only problem with this is that I would have preferred to use the JBoss 5 implementation and when going to JBoss 5 this will have to be re-written. If you are going to follow this Topic I would definetly consider what the impact of this type of implementation will cause when migrating.
