=Mapping Enums=
+
Java enums can be mapped to XML using the '''@XmlEnum''' and '''@XmlEnumValue''' annotations.
+
 
+
 
+
==Mapping enum constant name==
+
 
+
The following schema demonstrates an XML enumeration:
+
 
+
<source lang="xml">
+
<xs:simpleType name="CustomerType">
+
  <xs:restriction base="xs:string"/>
+
      <xs:enumeration value="PROMO_CUSTOMER"/>
+
      <xs:enumeration value="NEW_CUSTOMER"/>
+
      <xs:enumeration value="VIP"/>
+
      <xs:enumeration value="NORMAL"/>
+
</xs:simpleType>
+
</source>
+
 
+
If your enums constant names themselves are sufficient for the XML representation, you can simply use the '''@XmlEnum''' annotation:
+
 
+
<source lang="java">
+
@XmlAccessorType(XmlAccessType.FIELD)
+
public class Customer {
+
  @XmlElement(name="first-name")
+
  private String firstName;
+
 
+
@XmlEnum
+
public enum CustomerType { PROMO_CUSTOMER, NEW_CUSTOMER, VIP, NORMAL }
+
</source>
+
 
+
When marshalled to XML, an Person would look like this:
+
 
+
<source lang="xml">
+
<xs:simpleType name="Card">
+
  <xs:restriction base="xs:string"/>
+
      <xs:enumeration value="CLUBS"/>
+
      <xs:enumeration value="DIAMONDS"/>
+
      <xs:enumeration value="HEARTS"/>
+
      <xs:enumeration value="SPADES"/>
+
</xs:simpleType>
+
</source>
+
 
+
==Mapping enum constant name(value)==
+
This code:
+
 
+
<source lang="java">
+
    @XmlType
+
    @XmlEnum(Integer.class)
+
    public enum Coin {
+
        @XmlEnumValue("1") PENNY(1),
+
        @XmlEnumValue("5") NICKEL(5),
+
        @XmlEnumValue("10") DIME(10),
+
        @XmlEnumValue("25") QUARTER(25) }
+
</source>
+
 
+
will generate the following XML schema:
+
 
+
<source lang="xml">
+
    <xs:simpleType name="Coin">
+
      <xs:restriction base="xs:int">
+
        <xs:enumeration value="1"/>
+
        <xs:enumeration value="5"/>
+
        <xs:enumeration value="10"/>
+
        <xs:enumeration value="25"/>
+
      </xs:restriction>
+
    </xs:simpleType>
+
</source>
