[jboss-user] [JBoss AOP] - Re: Can't read parameter annotations through reflection

[dwl8]

Thank you both for your replies.

flavia, all my annotations are set to RetentionPolicy.RUNTIME. If only that was the issue... :)

stalep, I created a unit test and it read the annotation correctly. It seems that when I deploy it to my app server (Tomcat) the annotation can't be read. Here's a simple class I was using to recreate the issue.


  | public class Person {
  | 	private static HashMap<Integer,Person> peopleMap = new HashMap<Integer,Person>();
  | 
  | 	@ReadLock
  | 	public static Person getPerson(@FirmId Integer firmId) {
  | 		try {
  | 			Method m = Person.class.getMethod("getPerson",Integer.class);
  | 			Annotation[][] paramAnnot = m.getParameterAnnotations();
  | 			for(Annotation[] a : paramAnnot) {
  | 				System.out.println("# of Annotations Found: " + a.length);
  | 				//log.debug("# of Annotations Found: " + a.length);
  | 			}
  | 		} catch(NoSuchMethodException e) {
  | 			System.out.println("Method not found");
  | 			//log.debug("No Such Method");
  | 		}
  | 		return peopleMap.get(firmId);
  | 	}
  | 
  | 	public static void main(String[] args) {
  | 		try {
  | 			Method m = Person.class.getMethod("getPerson",Integer.class);
  | 			Annotation[][] paramAnnot = m.getParameterAnnotations();
  | 			for(Annotation[] a : paramAnnot) {
  | 				System.out.println("# of Annotations Found: " + a.length);
  | 				//log.debug("# of Annotations Found: " + a.length);
  | 			}
  | 		} catch(NoSuchMethodException e) {
  | 			System.out.println("Method not found");
  | 			//log.debug("No Such Method");
  | 		}
  | 	}
  | }
  | 

when main is run, i get "# of Annotations Found: 1". However, when I make a call to getPerson after it's been deployed to Tomcat, I get "# of Annotations Found: 0". Strange.

Could anyone give this code a whirl and keep me from losing my sanity?
