29.3. Annotations for component life cycle methods

@Create

@Create

Specifies that the method should be called when an instance of the component is instantiated by Seam. Create methods are only supported for JavaBeans and stateful session beans.

@Destroy

@Destroy

Specifies that the method should be called when the context ends and its context variables are destroyed. Destroy methods are only supported for JavaBeans and stateful session beans.

Destroy methods should be used only for cleanup. Seam catches, logs and swallows any exception that propagates out of a destroy method.

@Observer("somethingChanged")

@Observer("somethingChanged")

Specifies that the method should be called when a component-driven event of the specified type occurs.

@Observer(value="somethingChanged",create=false)

@Observer(value="somethingChanged",create=false)

Specifies that the method should be called when an event of the specified type occurs, but that an instance should not be created if it does not already exist. If an instance does not exist and create is set to false, the event will not be observed. The default value is true.
