Raise customized JBO exception from AM to Client

Question

All
I want to raise exception in am, vo or eo to client side when some kind of business rules hit. How can i raise the JBO exception with info to identify the failed root reason?
If execute the binding operation I can call the getErrors() to check if the last execute succeed or not. How can i get this error message when call the operation via web service which exported from am,
follow are the code part in DemoAMServiceImpl for example, the DemoAMServiceImpl is generated by default when export DemoAM to support web service:
public EventsVOSDO updateEventsVO1(EventsVOSDO eventsVO1) throws ServiceException {
return (EventsVOSDO)update(eventsVO1, "EventsVO1");
when call this method to update event via web service to update event in AM, logic in eventEO checks the event property and raise custom event to client to indicate failure.
any one have good ideals on this requirement?

Try something like this in your method:
throw new JboException("Don't do that.", "101", null );
