You are finally ready to move on to the business tier of the
application, where business logic is handled. The business tier is
made up largely of session beans, and you’ll use it
to build out the infrastructure of the Forethought application. This
tier will of course rest upon the structure already in place, and
will use this foundation for access to the database and directory
server. Expect to deal with lots of logic for handling user
administration, investments, transactions, account queries, and more
in the next section of the book; we’ll also look at
the Java Messaging Service (JMS) to handle communication of
time-sensitive data. Make sure your entity beans and
LDAPManager classes are ready to go, and dive
into the
next chapters.
