Another way to get the annotation associated with the executed action is
private static boolean isAnnotationPresent(ActionInvocation
actionInvocation,
Class annotationClass) {
return
getMethodFromInvocation(actionInvocation).isAnnotationPresent(
annotationClass);
}
private static Method getMethodFromInvocation(ActionInvocation
actionInvocation) {
Method method;
try {
method = actionInvocation.getAction().getClass()
.getMethod(actionInvocation.getProxy().getMethod());
// should never happen because struts would have failed before
this method call
//if the method didn't exist
} catch (SecurityException e) {
throw new RuntimeException(e);
} catch (NoSuchMethodException e) {
throw new RuntimeException(e);
}
return method;
}
