Error while deleting events from the integration event queue

Question

I am trying to delete all the events from the integration event queue after reading it, like this (this is in Java):
        IntegrationEventWS_DeleteEvents_Input input = new IntegrationEventWS_DeleteEvents_Input();
        input.setDateTime("");
        input.setLastEventId("");
        try {
             ((Default_Binding_IntegrationEventWS)onDemandStub).deleteEvents(input);
        } catch (Exception e) {
             log.error("Deleting events from integration queue failed: ", e);
        }Alas, I get the following error message:
Invalid method parameter(s): 'File Id'(SBL-ODS-50007)What does this mean? What is this mysterious "File Id" it supposedly gets? I don't see it anywhere in the SOAP message I'm sending and it isn't mentioned anywhere in the docs.
Thanks in advance for any input.

Answer 1

Dont keep this attributes null
input.setDateTime(""); //Put a Default Time way in
the past. Ex:"1/1/2000"
input.setLastEventId(""); //pass the eventIdThe documentation states that those two are optional (although they are not nillable, for some reason). I tried to set the date to today, but I got the same result. Since setting a date is supposed to delete all events older than that date, I don't think setting it in the past will delete anything.
