5.4. Life cycle methods

Session bean and entity bean Seam components support all common EJB3 life cycle callbacks (@PostConstruct, @PreDestroy, etc.), but Seam also supports the use of any of these callbacks with JavaBean components. However, since these annotations are not available in a J2EE environment, Seam defines two additional component life cycle callbacks, equivalent to @PostConstruct and @PreDestroy.
The @Create method is called after Seam instantiates a component. Components may define only one @Create method.
The @Destroy method is called when the context that the Seam component is bound to ends. Components may define only one @Destroy method.
In addition, stateful session bean components must define a method with no parameters, annotated @Remove. This method is called by Seam when the context ends.
Finally, the @Startup annotation can be applied to any application- or session-scoped component. The @Startup annotation tells Seam to instantiate the component immediately, when the context begins, instead of waiting until it is first referenced by a client. It is possible to control the order of instantiation of start up components by specifying @Startup(depends={....}).
