hm, even though i havent tested it myself but i thought it should work. the code you are calling is CtMethod/CtBehavior which is javassist, but thats not your problem :) have you tested .getAvailableParameterAnnotations() too? if that doesnt work either, could i bother you to make a small test to reproduce it (even though your example was nice a working test makes it much easier for me :) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3990951#...
