OK.

jboss-common-core.jar  and concurrent.jar

Sure.

OK. I will provides entries commented in the files and describe what to
remove/uncomment to have the app works with WAS v7

But as this sample is likely the application people start with, IMHO it
would be better to have an application that shows the "best way to run  Seam
on your AS".
eg, in the doc I will describe three ways to configure the application to
let Seam smoothy find the beans in the JNDI WAS namespace. If I give
instructions to modify the sample app "with minimal changes" (see your
comment below) to run on WAS, it will use the worse way (IMO) to do it (ie
maintain the ejb3 ref in the config files) and people will build their apps
on this without any real sample app that will use the best approach.
If you are OK with it, for WAS, I will give instructions to build the
booking application and get the "best way to run Seam on WAS v7", this will
include a few extra steps (like remove the ejb-ref etc..)

OK.
