Building Java Enterprise Applications

What’s Next?

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.
