It is part of the configuration information used todeploy your EJB, the topic of the next chapter.) But there are some seriouscomplications with entity beans that involve retrieving the bean’s data froma “backing store”—for example, a database—and writing it back. There aremany good references on these topics, and we mention our favorites in thenext section.22.5RESOURCESThese are some of our favorite resources for learning about and dealing withEJBs. All of these give much more extensive examples that we have space for,and we encourage you to look at one or more of them.• J2EE and Beyond by Art Taylor (Prentice Hall PTR, ISBN0-13-141745-2) gives a very good overview of all of the pieces of J2EE.At over 1,000 pages, it’s no small book, but it covers a lot more thanjust EJBs.• Enterprise JavaBeans Component Architecture: Designing and Coding Enterprise<strong>Application</strong>s by Gail Anderson and Paul Anderson, Sun MicrosystemsPress, ISBN 0-13-035571-2. At only 435 pages it is the most concise ofthe three, with the tightest focus and an emphasis on the code.• Applied Enterprise JavaBeans Technology by Kevin Boone, Sun MicrosystemsPress, ISBN 0-13-044915-6. At just over 700 pages, it is midway betweenthe other two titles. Like the Taylor book, it covers some related technologies,but gives more depth to EJBs than Taylor, as that is its focus. It providesmore examples than the Andersons, but its examples are not anydeeper, just broader.
