[jboss-user] [Javassist user questions] - Re: adding annotations

[cat4hire]

I'm going mad, anyone with a suggestion?

I've found that the following piece of code:


  | 	    ByteArrayOutputStream aos = new ByteArrayOutputStream();
  | 		    AnnotationsWriter aw = new AnnotationsWriter(aos, constantPool);
  | 		    aw.numAnnotations(1);
  | 		    aw.annotation(this.annotationClassName, 0);
  | 		    aw.close();
  | 		    byte ab[] = aos.toByteArray();
  | 		    System.out.println("\n\t++++Annotation bytecode  for annotation " + this.annotationClassName + "++++");
  | 		    System.out.println(new String(ab) );
  | 		    System.out.println("\n\t++++++++++++++\n");
  | 		    attribute = new AnnotationsAttribute(constantPool, AnnotationsAttribute.visibleTag, ab);
  | 

that should create the annotation specified, prints the following:


  | 
  | 	++++Annotation bytecode  for annotation whitecat.example.DBRoleAnnotation++++
  | 
  | 
  |        +++++++++++++++++++++++
  | 
  |  

So I'm pretty sure that the bytecode generated for the annotation is empty, and that the annotation is regularly added to my class, but without a bytecode I cannot access it. Anyone can explain why the bytecode is null?
