Binary Types

There are a few extra things to consider when mapping to fields of type byte[ ] or Byte[ ].


byte[ ] versus Byte[ ]

Unlike other Java primitive/wrapper types, Eclipselink differentiates between byte[ ] (primitive) and Byte[ ] (wrapper) data types. By default, byte[ ] will marshal to an element or attribute of type base64Binary, whereas Byte[ ] will marshal each byte as its own element.

package example;
 
import javax.xml.bind.annotation.*;
 
@XmlRootElement
public class BinaryData {
 
   public byte[] primitiveBytes;
   public Byte[] byteObjects;
 
}
BinaryData b = new BinaryData();
b.primitiveBytes = new byte[] {34,45,56,67,78,89,89,34,23,12,12,11,2};
b.byteObjects = new Byte[] {23,1,112,12,1,64,1,14,3,2};
 
jaxbContext.createMarshaller().marshal(b, System.out);


<?xml version="1.0" encoding="UTF-8"?>
<binaryData>
   <primitiveBytes>Ii04Q05ZWSIXDAwLAg==</primitiveBytes>
   <byteObjects>23</byteObjects>
   <byteObjects>1</byteObjects>
   <byteObjects>112</byteObjects>
   <byteObjects>12</byteObjects>
   <byteObjects>1</byteObjects>
   <byteObjects>64</byteObjects>
   <byteObjects>1</byteObjects>
   <byteObjects>14</byteObjects>
   <byteObjects>3</byteObjects>
   <byteObjects>2</byteObjects>
</binaryData>
