Maybe i have to override SimpleRequestProcessor.process(RequestMessage req,
ResponseMessage resp)
around
// Validate entities
List<ViolationMessage> errorMessages = validateEntities(source);
if (!errorMessages.isEmpty()) {
resp.setViolations(errorMessages);
return;
}
RequestState returnState = new RequestState(source);
// Invoke methods
List<Splittable> invocationResults = new ArrayList<Splittable>();
List<Boolean> invocationSuccess = new ArrayList<Boolean>();
*processInvocationMessages*(source, req, invocationResults,
invocationSuccess, returnState);
