[appfuse-user] AspectJ syntax for Appfuse 2

[dev dev]

what is this wildcard expression "*..service" mean and can someone point me
to the documentation on pointcut language and its regular expression
definition?

in the applicationContext-service.xml,

<aop:config>
        <aop:advisor id="userManagerTx" advice-ref="userManagerTxAdvice"
pointcut="execution(* **..service*.UserManager.*(..))" order="0"/>


Thanks
dev
