We've gone with Weblogic primarily because of
the clustering support.
Be aware that this does not only relate to the
issue of server location (DNS Round Robin, Load
balance etc), but also ensuring that a given
instance of an Entity bean only exists in one
of the servers in the cluster - which i think
is the more difficult bit.
