Avoid the "marshalling" of a field

[Lorenzo Carnevale]

I expose this class as an axis2 web service:

public Bean log(String string) throws RemoteException

{

    Bean b = new Bean();

    // do stuff....

    return b;

}

The class Bean is a plain pojo that contains some "useful" fields that I DON'T 
want to send back.

Can I tell somehow to Axis2 to NOT serialize (i.e. not to put it in the SOAP 
answer!) one or some of these fields contained in Bean? 

Thanks
