As Flavia said, if you are using loadtime weaving you need to "prepare" the joinpoints. This information must be available when the class is first loaded. Once the class is loaded we cannot modify the class. Meaning you cannot introduce more hooks for AOP once the class is loaded, but we can modify what aspects are applied to those hooks. A "prepare" is basically the same as an empty "bind". View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4085026#...
