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, as illustrated by the following example:
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>
