Where to begin? Your humble authors themselves are still learning the intrica-
cies of J2EE. We have more or less ignored message beans. We have not de-
scribed the local and local home interfaces, concentrating instead on the remote
access of beans. This is because remote access is what client applications will
most often use. But entity beans, for example, can only call one another
through the local interface, and, in practice, a session bean will likely provide
remote access but call any other beans through a local interface.
A quick examination of your local bookstore's computer topics section
will reveal that J2EE is a vast topic, just by the number of books on the topic
and their thickness. Our goal here is to give you enough to make a quick start
in using EJBs on a Linux-hosted application server. From there—well, those
thick topics are probably your next stop.
