[jboss-user] [Javassist] - Adding a Method Annotation not working as expected...

To view the discussion, visit: http://community.jboss.org/message/629947#629947 -------------------------------------------------------------- Hi All, I have a few classes ( in a supplied jar) in which I am trying to mark certain specifc methods as "Deprecated" . I am able to use javassist and add the annotation to the method (code attached to the end of this mail) but Eclipse refuses to identify that as a "Deprecated" method at compile time. I decompiled and verified that there is a "@Deprecated" annotation on the method. I also used ASM compare between a class in which I added a @Deprecated and this class in which javassist  added the annotation and notice one strange thing : the access flags are different "normal" method : // DEPRECATED   // access flags 0x20001   public getName()Ljava/lang/String;   @Ljava/lang/Deprecated;()    L0     LINENUMBER 7 L0   javassist annotated method :    // access flags 0x1   public getName()Ljava/lang/String;   @Ljava/lang/Deprecated;()    L0     LINENUMBER 7 L0   Questions : 1) is there a problem in the way the Annotation is being added ? 2) Cant I add a java.lang.Deprecated annotation to a method ? is there some special modifier or instruction to be used to add the inbuilt java Annotations ? Any help or pointer is appreciated !! I tried to make it a "invisibleTag" ,  specify it as "Deprecated" , "@Deprecated" but the IDE refuses to treat that as a Deprecated API. thanks Pat ---- code snippet : CtMethod[] methods = cc.getMethods();   for (int k = 0; k < methods.length; k++) {    CtMethod met = methods[k];     System.out.println("Found Method --> " + met.getName());     try{      ClassFile ccFile = cc.getClassFile();      ConstPool constpool = ccFile.getConstPool();           AnnotationsAttribute attr = new AnnotationsAttribute(constpool, AnnotationsAttribute.visibleTag);      Annotation annot = new Annotation("java.lang.Deprecated", constpool);      attr.addAnnotation(annot);      met.getMethodInfo().addAttribute(attr);                }catch(Exception e){      System.out.println("Skipping method:-->" + met.getName() +"Reason:" + e.getMessage() );     }   } -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/629947#629947] Start a new discussion in Javassist at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
