java - xjc: override xs:simpleType definition -

i compiling set of xsds java classes using xjc. able override data type definition given simple type. xsd snippet is:

<xs:simpletype name="cpt-datetime">     <xs:annotation>         <xs:appinfo>can specified integer number or xs:datetime</xs:appinfo>     </xs:annotation>     <xs:union membertypes="xs:unsignedlong xs:datetime"/> </xs:simpletype> 

which results (not surprisingly) in element of cpt-datetime type being defined in resulting java class string, e.g.

public class ccreporttraininitialization { ...     @xmlelement(required = true)     protected string time; ...     public string gettime() {         return time;     }      public void settime(string value) {         this.time = value;     } ... 

what datatype of time (in example) date-time specific type, e.g. xmlgregoriancalendar or that:

public class ccreporttraininitialization { ...     @xmlelement(required = true)     protected xmlgregoriancalendar time; ...     public xmlgregoriancalendar gettime() {         return time;     }      public void settime(xmlgregoriancalendar value) {         this.time = value;     } ... 

is possible?

i've been experimenting binding file i'm not sure it's possible do. suggestions?

further options are:

• jaxb:basetype
• jaxb:javatype
• xjc:javatype - jaxb:javatype allows specifying adapter class instead of unmarshal/marshal methods.

i argue jaxb:class/@ref customization not right simple type makes "class" type. matters internal xjc model, of xjc plugins may handle type incorrectly.

i think should use jaxb:javatype here. try:
