At the heart of any enterprise application lies its business logic. In an ideal world, application developers should only be concerned with defining and implementing the business logic, while concerns like presentation, persistence, or integration should largely be window dressing. From this perspective, session beans are the most important part of the EJB technology because their purpose in life is to model high-level business processes. If you think of a business system as a horse-drawn chariot with a driver carrying the Greco-Roman champion to battle, session beans are the driver. Session beans utilize data and system resources (the chariot and the horses) to implement the goals of the user (the champion) using business logic (the skills and judgment of the driver). For this and other reasons, sessions beans, particularly stateless session beans, have been popular, even despite the problems of EJB 2. EJB 3 makes this vital bean type a lot easier to use. In chapter 1 we briefly introduced session beans. In chapter 2 we saw simple examples of these beans in action. In this chapter, we ll discuss session beans in much greater detail, focusing on their purpose, the different types of session beans, how to develop them, and some of the advanced session bean features available to you. We start this chapter by exploring some basic session bean concepts, and then discuss some fundamental characteristics of session beans. We then cover each type stateful and stateless in detail before introducing bean client code. Finally, we examine session bean best practices at the end of the chapter.

1. On the right of the Properties panel you will see the Split View icon, shown in Figure 7-15.

There are a number of settings under general settings; click the SETTINGS tab to view all of them. The V erbose check box determines whether a message will be displayed when saving a node, taxonomy term, or user and when the URL is changed, as shown in Figure 7-3. This usually happens when, for example, a path pattern is based on the node title (for example, http://example.com/gallery/[node:title]) and the title is changed during a save. The Separator setting is the Unicode character placed between words in titles, including both spaces and punctuation such as colons or apostrophes. Generally speaking, I tend to use a hyphen so I can optimize my site for Google. This requires a bit of an explanation. When doing a search on Google for hello world (with a space), Google returns sites with both spaces and hyphens in the domain and page title. However, do a search for hello_world (with an underscore), and Google returns sites with the underscore; it does not return any sites with dashes or spaces. If you want people to find your page on the Internet by searching Google using hello world, then it s best to use a hyphen. However, there are times when it s important for an underscore to appear in search results, such as when people search specifically for hello_world. By

A typical enterprise application will have numerous business activities or processes. For example, our ActionBazaar application has processes such as creating a user, adding an item for auctioning, bidding for an item, ordering an item, and many more. Session beans can be used to encapsulate the business logic for all such processes. The theory behind session beans centers on the idea that each request by a client to complete a distinct business process is completed in a session. So what is a session If you have used a Unix server you may have used Telnet to connect to the server from a PC client. Telnet allows you to establish a login session with the Unix server for a finite amount of time. During this session you may execute several commands in the server. Simply put, a session is a connection between a client and a server that lasts for a finite period of time.
