There is little doubt that stateful session beans provide extremely robust business logic processing functionality if maintaining conversational state is an essential

application requirement In addition, EJB 3 adds extended persistence contexts specifically geared toward stateful session beans (discussed in chapters 9 and 13), significantly increasing their capability Most popular application servers such as WebSphere, WebLogic, Oracle, and JBoss provide high availability by clustering EJB containers running the same stateful bean A clustered EJB container replicates session state across container instances If a clustered container instance crashes for any reason, the client is routed to another container instance seamlessly without losing state Such reliability is hard to match without using stateful session beans Nonetheless, there are a few things to watch out for while using stateful session beans Choosing session data appropriately Stateful session beans can become resource hogs and cause performance problems if not used properly.

Since the container stores session information in memory, if you have thousands of concurrent clients for your stateful session bean you may run out of memory or cause a lot of disk thrashing by the container as it passivates and activates instances to try to conserve memory Consequently, you have to closely examine what kind of data you are storing in the conversation state and make sure the total memory footprint for the stateful bean is as small as possible For example, it may be a lot more efficient to store just the itemId for an Item instead of storing the complete Item object in an instance variable If you cluster stateful beans, the conversational state is replicated between different instances of the EJB container State replication uses network bandwidth.

Navigate to the Configuration page and select Webform settings under the CONTENT AUTHORING header. Your first set of configuration settings are Webform-enabled content types, as shown in Figure 7-26. By default, the module creates and enables a content type called Webform.

Storing a large object in the bean state may have a significant impact on the performance of your application because the containers will spend time replicating objects to other container instances to ensure high availability We ll discuss more about EJB clustering in chapter 13 Passivating and removing beans The rules for passivation are generally implementation specific Improper use of passivation policies (when passivation configuration is an option) may cause performance problems For example, the Oracle Application Server passivates bean instances when the idle time for a bean instance expires, when the maximum number of active bean instances allowed for a stateful session bean is reached, or when the threshold for JVM memory is reached You have to check the documentation for your EJB container and appropriately set passivation rules For example, if we set the maximum number of active instances allowed for a stateful bean.

instance to 100 and we usually have 150 active clients, the container will continue to passivate and activate bean instances, thus causing performance problems. You can go a long way toward solving potential memory problems by explicitly removing the no longer required bean instances rather than depending on the container to time them out. As discussed earlier, you can annotate a method with the @Remove annotation that signals the container to remove the bean instance. Given the fact that stateful session beans can become performance bottlenecks whether through improper usage or under certain circumstances, it is worth inspecting the alternatives to using them.
