VB/Apache problem-- void Java method always cause VB Client to fa il.

["Ding, Chengmin" <Ch...@tfn.com>]

Hi, All,
I am using a VB client to invoke an Apache Web service.
The service I am using doesn't return any thing, so inside the service it is
a void function.
The VB client tried to invoke this service via the following call 
	soapclient.updateVIS(BatchID)
But it always caused the following error in VB:
	automation error
	unspecified error
I checked the return envelop and it looks fine(please see below). And on the
server side the service has performed the correct update operation. Then I
changed the updateVIS service to return a string and everything works fine.
So I want to know whether any of you
have encountered a similar problem? Does MS SOAP always requires a
Request/Response message model? It looks like the Request only way doesn't
work. 
Any of your input is highly appreciated.

Thanks.
