In vendor selection, you have two groups to consider, commercial, well
established vendors and open source / very low cost (OS / VLC) vendors. The
pros / cons between these two are fairly clear cut:
Commercial Pros
Good support
Higher standard of documentation (generally)
Good market penetration (so hiring experienced developers etc. is easier)
You can be sure they'll be around next year to answer your questions
Some vendors who are on the expert groups at Javasoft, obviously use this
knowledge to make sure they protect their interests (and by extension yours)
as the new specs. unfold by either supporting them in released products or
getting beta versions roadtested early
Commercial Cons
High initial cost of ownership (over time however, this should lessen)
Some commercial vendors are slow to support the new specs. as they are
released (in contrast to the pro listed above)
Some commercials have been around a while and thus are not 100% Java
(usually having C++ components), each vendor should make this clear in the
docs however.
OS / VLC Pros
Low / zero initial cost of ownership
Small and nimble enough to turn on a penny when it comes to spec. conformity
and new features
All (AFAIK) are 100% Java
OS / VLC Cons
Documentation can be poor compared to commercial
It's harder to find developers who know the server
Support is not clear cut and must be considered a risk, particularly if you
are consulting and will be handing the finished software off to a client
(who may not have a strong skillset in-house).
In order to avoid missing any one vendor out, here's a pretty complete list
of links for app. servers with follow-on links etc.:

My own personal opinion is that I'd still spec. a commercial vendor for at
least the next 6 - 12 months, but I play around with servers like Orion and
jBoss in the meantime and lurk on the lists to see how stable they are (;-))

Subject: J2EE - Server
Servus,
we are going to start developing a B2B - "portal" and we have decided to use
J2EE - EJB - technology.
Now, besides our concrete design, we are thinking about what server we
should use. The server shoul dmake it possible to develop 100% pure Java -
"apps" and to do that in an as standardized way as possible, so that we can
change the server without too much trouble if needed.
Has anyone any hints URLs and so on, that could help us to take the
decission?
Thanks in advance
Wolfgang Egger
