Configuring a Lifecycle Callback Method for an EJB 3.0 Session Bean

You can specify an EJB 3.0 session bean class method as a callback method for any of the following lifecycle events (see "Using Annotations"):

• Post-construct: a method called before the first business method invocation on the session bean and after OC4J performs any dependency injection.

• Pre-destroy: a method called before OC4J removes the session bean. Typically, you use this method to release any resources that your session bean is holding.

• Pre-passivate: a method called before OC4J passivates the session bean. Applicable to stateful session beans only. Use only if you need to close resources prior to passivation.

• Post-activate: a method called immediately after OC4J reactivates a formerly passivated session bean. Applicable to stateful session beans only. Use only if you need to reopen resources after reactivation.

The session bean class lifecycle callback method must have the following signature:

public void <MethodName>()

For more information, see "Callback Methods".

@Stateful
public class CartBean implements Cart
{
    private ArrayList items;
 
    @PostConstruct
    public void initialize()
    {
        items = new ArrayList();
    }
...
}
