我已将WSDL（http://services.cuberoute.com/axis2/services/ShipmentService.wsdl）导入Visual Studio中的.net项目中作为Web参考。我创建我的ShipmentRequest。当我尝试使用ShipmentService提交请求时，得到的响应为“ null java.lang.NullPointerException”。
Dim address As New Descartes.Address
address.addressLine1 = "1 North Road"
address.addressLine2 = ""
address.city = "Boston"
address.stateCode = "MA"
address.postalCode = "02115"
address.countryCode = "USA"
Dim item As New Descartes.Item()
item.description = "Item"
item.custom = "XS001-P9930"
item.pieceCount = 1
item.weight = 300
Dim invoice As New Descartes.Invoice
invoice.custom = "9991009"
invoice.comment = ""
invoice.name = ""
invoice.items = {item}
Dim requiredDate As New Descartes.Attribute
requiredDate.name = "RequiredDate"
requiredDate.value = "08/10/2019"
Dim transaction As New Descartes.ShipmentRequest()
transaction.operationCode = Descartes.Operation.Edit
transaction.address = address
transaction.customerFirstName = ""
transaction.customerFirstName = ""
transaction.customerCompanyName = "Company name"
transaction.customerID = "99999"
transaction.invoices = {invoice}
transaction.shipmentTypeSpecified = True
transaction.shipmentType = Descartes.ShipmentType.CustomerDelivery
transaction.scheduledDeliveryDate = "2019-08-10T12:00:00"
transaction.sellingStoreNumber = "100002"
transaction.fulfillingStoreNumber = "100002"
transaction.username = "XXXXX"
transaction.passwordHash = "XXXXX"
transaction.organizationKey = "XXXXX"
Dim ship As New Descartes.ShipmentService
Dim the_response As Descartes.ShipmentResponse()
the_response = ship.shipment({transaction})
Response.Write(the_response(0).response.responseCode & "<br>")
Response.Write(the_response(0).response.responseDescription & "<br>")
错误是：
responseCode = 1
responseDescription = null
java.lang.NullPointerException
