I'm not sure about the use of an agent, because it will perform the annotation addition at the program load time, while I have to perform it depending on run-time conditions at class loading time, and most important I could have separate class loaders that add or not the annotations to the class they are loading. Is this possible with the agents? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4131005#...
