java.net.URI Type

Guideline: Use the @XmlSchemaType annotation for a strongly typed binding to a .NET client generated with the DataContractSerializer.

java.net.URI maps to xs:string. .NET maps xs:string to System.string. Annotation @XmlSchemaType can be used to define a more strongly typed binding to a .NET client generated with the DataContractSerializer. @XmlSchemaType can be used to map java.net.URI to xs:anyURI. .NET’s DataContractSerializer and XmlSerializer bind xs:anyURI differently:

• DataContractSerializer binds xs:anyURI to .NET type System.Uri.

• XmlSerializer binds xs:anyURI to .NET type System.string.

Thus, the above technique only works if the WSDL is processed using DataContractSerializer.

Example: @XmlSchemaType and DataContractSerializer

// Java code fragment
public class PurchaseOrder
{
    @XmlSchemaType(name="anyURI")
     public java.net.URI uri;
}

//-- Schema fragment
<xs:complexType name="purchaseOrder">
    <xs:sequence>
        <xs:element name="uri" type="xs:anyURI" minOccurs="0"/>
    </xs:sequence>
</xs:complexType>

//--- .NET auto generated code from schema
//--- Using svcutil.exe /serializer:DataContractSerializer <wsdl file>
public partial class purchaseOrder : object,
        System.Runtime.Serialization.IExtensibleDataObject
{

    private System.Uri uriField;

    //-- ..... other generated code ........
    public System.Uri uri
    {
        get { return this.uriField; }
        set { this.uriField = value; }
    }
}

//--- C# code fragment
purchaseOrder tmpU = new purchaseOrder()
tmpU.uri = new System.Uri("../Hello", System.UriKind.Relative);

Example:@XmlSchemaType and XmlSerializer

// Java code fragment
public class PurchaseOrder
{
    @XmlSchemaType(name="anyURI")
    public java.net.URI uri;
}

//--- .NET auto generated code from schema
//--- Using svcutil.exe /serializer:XmlSerializer <wsdl file>
public partial class purchaseOrder
{
    private string uriField;
    public string uri
    {
        get { return this.uriField; }
        set { this.uriField = value; }
    }
}

//--- C# code fragment
purchaseOrder tmpU = new purchaseOrder()
tmpU.uri = "mailto:mailto:mduerst@ifi.unizh.ch";
