Here is what I have in mind: as each attribute is loaded from the source xml the location from where it was loaded is remembered. When an attribute is changed that was loaded from the xml, the persistence manager overwrites the existing XML. I don't think you have to explode the jar, but I do think you basically have to rewrite the entire file. I think the trick will be to convince the auto deployer to not redeploy the modified file (if you can't figure that out it is ok... I get David J to get it to work :-)
Does this sound do-able?

Matt,
I think we want seemless integration here. If the MBean is packaged within a SAR, the SAR should be exploded, the XML file modified and the SAR re-jared. Same goes with straight XML files or SARS embedded within SARs (russian doll).
I'm in the process of creating task lists at SourceForge for each project. I can assign you this task?
Thanks for your effort,

Yeah, I suppose I could put some more time into it. It sounds like you know a few people that might actually be users of this feature. Do you have a use case in mind?
