how to exclude a caller in interceptor

[john_woo]

Hi,

My app based on ejb3 (one of them is message driven bean).

We define some interceptors for all session beans, but how can we achieve such that if caller is MDB, then bypass all intercepting stage. like

<interceptor-binding>
<ejb-name>myService</ejb-name>
<interceptor-class>com.myInterceptor</interceptor-class>
<exclude-caller>MDBname or MyMDBclass
</interceptor-binding>

Thanks
John

you could try something like:

<typedef
 name="intercept_this"
 expr="class(my.package.*)"/>

<typedef
 name="dont_intercept"
 expr="class($instanceof{@MessageDriven})"/>

<pointcut name="myPointcut"
 expr="execution(public * $typedef{intercept_this}->*(..))
 AND !execution(publiic * $typedef{dont_intercept}->*(..))"/>

<bind pointcut="myPointcut">
 <interceptor class="the.interceptor.MyInterceptor"/>
</bind>

notice the use of AND along with the !(not).

Thanks lots.
Can you tell where I can find more examples and the explanation for the descriptor?
