The method annotated with PreDestroy is typically used to * release resources that it has been holding. This annotation MUST be * supported by all container managed objects that support PostConstruct * except the application client container in Java EE 5. The method on which * the PreDestroy annotation is applied MUST fulfill all of the following * criteria: *
*
* void <METHOD>(InvocationContext) *
* Object <METHOD>(InvocationContext) throws Exception *
* Note: A PreDestroy interceptor method must not throw application * exceptions, but it may be declared to throw checked exceptions including * the java.lang.Exception if the same interceptor method interposes on * business or timeout methods in addition to lifecycle events. If a * PreDestroy interceptor method returns a value, it is ignored by * the container. *
