OK, you saw my last email ( in the "JSR/SAR (Jetty) Undeployment..." thread)
right?
Well then expanding a little, this is what I had envisioned...

1- keep it simple. in a sar you can have a directory called "root" in the
META-INF dir, everything that is in this directory is copied exactly to
${jboss.system.deployed}\sarname\root
I think we then add a method to ServiceMBeanSupport that looks up this
directory, this way it can be set by the ServiceDeployer if the mbean being
deployed extends ServiceMBeanSupport (or implements the ServiceMBean
interface) and is easy for clients to find.
All the jars in the sar are also copied to ${jboss.system.deployed}\sarname
to avoid the file sharing violations that prevent the user from simply
moving the original file to undeploy. This is under the assumption that all
required classes are now in jars, I guess we can copy plain class files too,
but jars would be neater I reckon.
2- not sure what you mean? the above paragraph maybe.
3- I think (again going for simple) that when the sar is redeployed nothing
from the directory structure is overwritten, but the jars are. This way any
persistent data in the directory structure is kept and any configuration
files the user wants to update manually can be updated in the expanded
directory structure and when the sar is redeployed the new configuration
will take effect. If the user wants the files from the sar to be copied
over all they have to do is delete the ones in the deployed directory before
they redeploy their app.
I think this will pretty much allow us to do we want to do.

I am away all from work all next week, so I won't be able to do anything and
when I get back chances are I will have a stack of stuff to catch up on etc,
so its not really looking good. I do have time today to look at some simple
stuff. In fact I think I can come up with a simple dependency mechanism for
the AutoDeployer which will clean up a lot of those issues by handling it
all in one place. That will just leave the service deployer changes to do.
If people don't mind leaving it a couple of weeks I might be able to get
back to it.
That's the best I can do at the moment, my priorities have to be keeping on
top of any reported bugs in JBossMQ and our developments at work.
David.
