21.5. What You Still Don't KnowWhere to begin? Your humble authors themselves are still learning the intricacies of J2EE. We have more or less ignored message beans. We have not described 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 books 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 therewell, those thick books are probably your next stop. |
