Problem is to keep both (Tomcat and JBossAS) in sync, we need a similar
solution so we can easily compare both.

I think it depends if you want to use ear plugin or not.
We need to know if ear plugin provides full control over the dependencies it aggregates
or do something transitive. If it does something transitive it would be preferable to
package an ear the same way I did for tomcat. In addition you would have to maintain the
EAR descriptor file (or maybe generate it from the POM with a processing instruction
allowing to include or exclude a jar).
If EAR plugin is good then I think you are not far from solution but I have not tried
Martin's ear.
If you go with more handcrafted ear as described, you could reuse large part of the work
but perform additional filtering of jar files as likely some of them are included in JBoss
AS.
In both case I don't think it is too much work.
I think also that using only ANT would be good for consistence of the solution and it is
at the end a straightforward solution although it bypass Maven's habits.
