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? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4134189#...
