Hey guys, We are probably making a very stupid mistake but since we are new with webservices and we really can not figure out how to do this I will ask it anyway. We are modelling a Control Tower in a logistics chain. Now we want to send an order containing basic information (product en quantity) to a distribution center. For this we have created a webservice, with xml mapping etc. These are shown below. This is the xsd file for our mapping <?xml version="1.0"?> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" targetNamespace="http://www.w3schools.com" xmlns="http://www.w3schools.com" elementFormDefault="qualified"> <xs:element name="Order" type="OrderData"/> <xs:complexType name="OrderData"> <xs:sequence> <xs:element name="OrderNumber" type="xs:string"/> <xs:element name="ProductList" type="LoadData" minOccurs="0" maxOccurs="unbounded"/> </xs:sequence> </xs:complexType> <xs:complexType name="LoadData"> <xs:sequence> <xs:element name="Quantity" type="xs:positiveInteger"/> <xs:element name="Products" type="ProductData"/> </xs:sequence> </xs:complexType> <xs:complexType name="ProductData"> <xs:sequence> <xs:element name="Product" type="xs:string"/> </xs:sequence> </xs:complexType> </xs:schema> This is our xml mapping Our webservice looks as follows We get the following errors: com.mendix.integration.WebserviceException:
