XML Schema
<?xml version="1.0" encoding="UTF-8"?> <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <xsd:element name="customer" type="customer-type"/> <xsd:complexType name="customer-type"> <xsd:sequence> <xsd:element name="picture" type="xsd:hexBinary"/> <xsd:element name="resume" type="xsd:base64Binary"/> </xsd:sequence> </xsd:complexType> </xsd:schema>

Code Sample
XMLField pictureField = new XMLField("picture/text()") pictureField.setSchemaType(XMLConstants.HEX_BINARY_QNAME);

Setting custom conversion pairs: By default in TopLink XML built-in schema types are associated with java classes and vice versa. These default pairs can be modified by the user using the addJavaConversion and addXMLConversion api. For example by default a java.util.Calendar is mapped to the dateTime schema type so the XML will be formated based on that type. Below are the default schema type to java type conversion pairs and the default java type to schema type conversion pairs.

XML schema type to Java type default conversion pairs

Schema Type	Java Type
base64Binary	byte[]
boolean	boolean
byte	byte
date	java.util.Calendar
dateTime	java.util.Calendar
decimal	java.math.BigDecimal
double	double
float	float
hexBinary	byte[]
int	int
integer	java.math.BigInteger
long	long
QName	javax.xml.namespace.QName
time	java.util.Calendar
unsignedByte	short
unsignedInt	long
unsignedShort	int
anySimpleType	java.lang.String

Java type to XML schema type default conversion pairs

Java Type	Schema Type
