Apparently the decision to move to Tomcat was simply one of
standardization.  I think perhaps the decision was made a while back.
At any rate it was made without me for reasons I do not know.  I was
told though, when I mentioned being worried that such limits could
increase development effort, that I can use whatever libraries or
extensions I need.  This includes things like OpenEJB etc...

After learning more about these buzzwords and what they actually
implement though I'm starting to wonder what is left for EJB.  I can
replace standard Java EE JPA with Hibernate as it implements it now.
I can pull in JSF with either the standard implementation or MyFaces
(and tobago or whatever looks pretty interesting).  I can get
dependency injection with CDI; I'm thinking this gives me all the
advances in unit testing that EJB 3.1 gave us.  I can get @WebService
with JAX-WS though I might not even want it.

Unfortunately, if I use OpenEJB I'm stuck with an older Tomcat as it
doesn't work with 7.0 yet.  I tried a patched version that someone
released and it kind of worked I thought, but yesterday I found that
webservices were bugging out...either that or need a totally different
way of setting them up that would likely be a nightmare to figure
out.  I spent a good day on it yesterday just trying to get the ejb
example webservices to work and the way I fixed it was to stop trying
to use a patched version and just downgrade Tomcat.

I'd rather not base a new project on old technology that's just going
to end up obsolete the next release if I can at all help it.

Another thing about the previous technologies I listed is that I can
put them in my app's WEB-INF folder; I don't have to install them in
Tomcat.  Perhaps OpenEJB is the same way but I've not seen clear
documentation on doing so.

What is it that EJB offers me that I don't get with these other
standard technologies?  I thought it was things like SessionBeans and
such, but if I use the CDI and JSF bits it seems like I get a lot of
the same behavior because I've got @ManagedBean or @Named.  I'm
finding this confusing.
