Independently configure date format for XML/JSON serialization

Question

How do I configure the date format independently for each of my date fields?
For example, let's say I have a CustomerOrder class with more than 1 java.util.Date fields in it.
I need to be able to render like this:
<customerOrder>
<orderDate>2013-01-04T20:50:42.769Z</orderDate>
<user>Bob</lastUpdateUser>
<state>CO</state>
<estShipDate>2013-01-04</estShipDate>
</customerOrder>
So one of the dates may not care about the hh:mm:ss.
i.e. I cannot format every date the same way.
Any ideas?
This is my technology stack:
- Tomcat 7
- Jersey 1.16
- Enunciate 1.26.2
- Spring 3.1.2
- Hibernate 4.1.7
- JPA 2.0.3

Otis,
A "java.sql.Date" contains only a date, whereas a "java.sql.Timestamp" contains both date and time. So retrieve the data (from the database) as a "Timestamp" and not as a "Date".
Perhaps if you'd care to post the relevant part of your code and show what you are getting and what you want to get, I may be able to help you further.
Here's a small (uncompiled and untested) example:
Connection conn = // However you get it.
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("select sysdate from dual");
if (rs.next()) {
  Timestamp ts = rs.getTimestamp(1);
}Good Luck,
Avi.
