| /** |
| * The PostConstruct annotation is used on a method that needs to be executed |
| * after dependency injection is done to perform any initialization. This |
| * method MUST be invoked before the class is put into service. This |
| * annotation MUST be supported on all classes that support dependency |
| * injection. The method annotated with PostConstruct MUST be invoked even |
| * if the class does not request any resources to be injected. Only one |
| * method can be annotated with this annotation. The method on which the |
| * PostConstruct annotation is applied MUST fulfill all of the following |
| * criteria: |
| * <ul> |
| * <li>The method MUST NOT have any parameters except in the case of |
| * interceptors in which case it takes an InvocationContext object as |
| * defined by the Interceptors specification.</li> |
| * <li>The method defined on an interceptor class MUST HAVE one of the |
| * following signatures: |
| * <p> |
| * void <METHOD>(InvocationContext) |
| * <p> |
| * Object <METHOD>(InvocationContext) throws Exception |
| * <p> |
| * <i>Note: A PostConstruct 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 |
| * PostConstruct interceptor method returns a value, it is ignored by |
| * the container.</i> |
| * </li> |
| * <li>The method defined on a non-interceptor class MUST HAVE the |
| * following signature: |
| * <p> |
| * void <METHOD>() |
| * </li> |
| * <li>The method on which PostConstruct is applied MAY be public, protected, |
| * package private or private.</li> |
| * <li>The method MUST NOT be static except for the application client.</li> |
| * <li>The method MAY be final.</li> |
| * <li>If the method throws an unchecked exception the class MUST NOT be put into |
| * service except in the case of EJBs where the EJB can handle exceptions and |
| * even recover from them.</li></ul> |
