A very usefull feature in JAXB/JAXWS in code first approach is to use
Enumeration to define some specific set in XML-SCHEMA ie :

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "AchatVente", namespace = "http://myapp/services/v1/")
public enum BuySell {
    B("B"), S("S");

    private String value;

    BuySell (String v) {
         value = v;
    }

    public String value() {
        return value;
    }

    public static BuySell fromValue(String value) {
        for( BuySell av : BuySell .values() ) {
              if ( av.value().equals(value) )
                    return av;
        }

        return A;
    }
}


==>

<xs:simpleType name="BuySell ">

        <xs:restriction base="xs:string">
<xs:enumeration value="B"/>
<xs:enumeration value="S"/>
</xs:restriction>
</xs:simpleType>


Did there is a way to do the same dynamically
(xs:restriction/xs:enumeration), not using Enumeration but using
standard Java classes (these one grabbing their possible values at
runtime, ie from SQL backend).
