[jboss-dev-forums] [Design of POJO Server] - Re: ManagedObjects of ManagedObjects, etc.

[scott.stark@jboss.org]

My view of this was that one had to define the ManagedPropertys that exist on the attachments making up the parsed DeploymentUnit, and these would make up the DeploymentUnit ManagedObject. What is missing in your version of the ManagedProperty that I had in the ManagedPropertyRef was a notion of a context that allowed for classification of the ManagedPropertys into subsets. For example, just the DataSource/URL or DataSource/Pool set of properties.

The requirement for a split view you mention is what is problematic, and I'm not sure its needed. That multiple deployment descriptors can affect a given attachment metadata property is something that may need to be audited, but I don't see that these need to be kept as distinct changes. If I have a deployment whose parsed DeploymentUnit metadata attachments produce an ejb property x, the deployment level setting that produced x is only relevant for debugging. As a queriable aspect of the management api its a cumbersome starting requirement. If we want to get such a thing, we would have to have a property change event notion that has sufficient info to tie into the property mapping api to allow this to be determined.
