Can JAX-WS map an XSD date (xs:dateTime) to a Java Calendar?

Can JAX-WS map an XML schema date (xs:dat开发者_开发百科eTime), including its time zone, to a Java Calendar?

Yes, it can.

Contract first approach
You need to use the jaxb:javaType element. There's some general information here and an example of what you need to do here.

Contract last approach

@WebMethod(operationName = "getTest")
public Calendar getTest(@WebParam(name = "input") Calendar input) {
  input.roll(Calendar.DAY_OF_YEAR, 1);
  return input
}

Will map to:

<xs:complexType name="getTest">
  <xs:sequence>
    <xs:element name="input" type="xs:dateTime" minOccurs="0"/>
  </xs:sequence>
</xs:complexType>

<xs:complexType name="getTestResponse">
  <xs:sequence>
    <xs:element name="return" type="xs:dateTime" minOccurs="0"/>
  </xs:sequence>
</xs:complexType>

I would think it would work by default; JAXB (data binder that JAX-WS implementations use) should know how to convert between XML values and java.util.Calendar.

If not, the default date/time datatype used with XML is javax.xml.datatype.XMLGregorianCalendar, which can be converted using method toGregorianCalendar() (which will be of type java.util.GregorianCalendar, a java.util.Calendar subclass). So one possibility is to get data bound to XMLGregorianCalendar, then just convert back/forth when accessing. This can also be automated by using XMLJavaTypeAdapter.
