I am having some issues with the example provided:

i declared the parent <aop:declare-parents> as described in the book for all performers but it keeps complaining the receiveAward not found in kenny: code written in config file is as follows:

<aop:config>

<aop:aspect>
<aop:declare-parents types-matching="springidol.Performer+" >
implement-interface="springidol.Contestant"
default-impl="springidol.GraciousContestant"/>
</aop:aspect>

<aop:aspect ref="kenny">

<aop:pointcut id="perforjuggling" expression="execution(* springidol.Performer.perform(..))" />

<aop:after pointcut-ref="perforjuggling" method="receiveAward"/>

</aop:aspect>
...........
Errors:
