</soapenv:Body>
</soapenv:Envelope>
But I get error:
The formatter threw an exception while trying to deserialize the message:
There was an error while trying to deserialize parameter
http://tempuri.org/:Delivery.
The InnerException message was 'There was an error deserializing the
object of type DreamLogisticsService.Delivery.
The value '' cannot be parsed as the type 'Int32'.'.
What is the problem? Is the values not converted to INT on the requesting server?
Please help!

Answer 1

Your Delivery element has a number of sub-elements which are of types which cannot be passed an empty string as a value. Either remove the elements from your XML (they have a minOccurs property value of 0) or set them to an accepted value. E.g. OrderType is of type Int, OrderValue is of type Decimal, and both RestOrder and ReturnOrder are of type Boolean.
See your XSD here for type information: http://service.dreamlogistics.se/service.svc?xsd=xsd2
