The Java EE 5 Tutorial

Datatype Converter Example

The Datatype Converter example is very similar to the Customize Inline example. As with the Customize Inline example, the customizations in the Datatype Converter example are made by using inline binding declarations in the XML schema for the application, po.xsd.

The global, schema, and package, and most of the class customizations for the Customize Inline and Datatype Converter examples are identical. Where the Datatype Converter example differs from the Customize Inline example is in the parseMethod and printMethod used for converting XML data to the Java int data type.

Specifically, rather than using methods in the custom MyDataTypeConverter class to perform these data type conversions, the Datatype Converter example uses the built-in methods provided by javax.xml.bind.DatatypeConverter:

<xsd:simpleType name="ZipCodeType">
        <jxb:javaType name="int"
  <xsd:restriction base="xsd:integer">
    <xsd:minInclusive value="10000"/>
    <xsd:maxInclusive value="99999"/>
