faults and exceptions

["Melzer, Steven" <St...@paymentech.com>]

all,
 
i cannot find a good example explaining the relationship between faults and exceptions.  
 
in the axis fault example, the fault is a RemoteException with a get/setInfo method.  is this method required?  does Axis know how to call this method and create the fault message line from it, or is there more to it.  also, how do you set the fault error code, the fault details, etc.
 
i want to report back to the client a variety of exceptions from the server such as SQLExceptions, NullPointerExceptions, and service-specific exception.
 
thanks,
steve
