The same problem exists in all versions. I was using AS5.0
as an example.

As for the correct way to do it, look at how the
MC/deployers are integrated.

The jars are provided with suitable integration hooks 
- a SPI (system programmer interface) e.g. MainDeployer,
classloading, parsing, etc.

These are well defined and "stable" interfaces,
implementations and helpers
(I quote stable because we still haven't done our CR1
release yet 

The AS project (system and system-jmx) then uses (and
extends them
in some places - e.g. legacy jmx integration) them.

The deployments (the configuration files) are created by the
appserver project
where it can modify the behaviour to suit its own
requirements.

In principle your project should not have to change. Instead
what changes
is the way it is integrated into the different releases of
the appserver
(using the mechanism defined by that version/release).

For your "community updates" this should just be
case of replacing the jars
if you have paid any attention to the backwards (and
forwards) compatibility
of your spi.

ANOTHER ASIDE:

In principle, going forward, the jboss-integration project
should define
a webservices spi (interfaces and helpers) which you (or
anybody
else) can implement to provide webservices for any jboss
project that
integrates using our standard spi (e.g. AS, embedded, esb,
etc.)

It would then be a case of writing a JBoss4 subdeployer or a
JBoss5 deployer
on top of that spi. (I doubt it will ever get done for
JBoss4 

This would then embody the three different roles 
(currently you do all three yourself):

* Policy - what needs doing (the user - e.g. JBossAS)
* Wiring - How to go about doing it (the api/spi - e.g.
jboss-integration)
* Implementation - Do it (you - JBossWS)
