Binary Types

Guideline: java.awt.Image, javax.xml.transform.Source, and javax.activation.DataHandler map to xs:base64Binary. .NET maps xs:base64Binary to byte[].

JAXB 2.0 provides the annotation @XmlMimeType, which supports specifying the content type, but .NET ignores this information.

Example: Mapping java.awt.Image without @XmlMimeType

//-- Java code fragment
public class Claim {
    public java.awt.Image photo;
}

//-- Schema fragment
<xs:complexType name="claim">
    <xs:sequence>
        <xs:element name="photo" type="xs:base64Binary" minOccurs="0"/>
    </xs:sequence>
</xs:complexType>

//-- .NET auto generated code from schema
public partial class claim : object,
        System.Runtime.Serialization.IExtensibleDataObject
{
    private byte[] photoField;
    //-- ..... other generated code .......
    public byte[] photo
    {
        get { return this.photoField; }
        set { this.photoField = value; }
    }
}

//-- C# code fragment
try
{
    claim tmpC = new claim();

    System.IO.FileStream f = new System.IO.FileStream(
        "C:\\icons\\circleIcon.gif", System.IO.FileMode.Open);
    int cnt = (int)f.Length;
    tmpC.photo = new byte[cnt];
    int rCnt = f.Read(tmpC.photo, 0, cnt);

}
catch (Exception e)
{
    Console.WriteLine(e.ToString());
}

Example: Mapping java.awt.Image with @XmlMimeType

//-- Java code fragment
public class Claim {
    @XmlMimeType("image/gif")
    public java.awt.Image photo;
}

//-- Schema fragment
<xs:complexType name="claim">
    <xs:sequence>
        <xs:element name="photo" ns1:expectedContentTypes="image/gif"
                    type="xs:base64Binary" minOccurs="0"
                    xmlns:ns1="http://www.w3.org/2005/05/xmlmime"/>
    </xs:sequence>
</xs:complexType>

//-- Using the @XmlMimeType annotation doesn’t change .NET 
//--auto generated code
public partial class claim : object,
        System.Runtime.Serialization.IExtensibleDataObject
{
    private byte[] photoField;
    //-- ..... other generated code .......
    public byte[] photo
    {
        get { return this.photoField; }
        set { this.photoField = value; }
    }
}

//-- This code is unchanged by the different schema
//-- C# code fragment

{
    claim tmpC = new claim();
