the relevant stuff is mainly in javax.xml.bind package. include by default in JDK6, versions vary. tools like schemagen are not, so need to be downloaded from jaxb site.

basic example:

@XmlRootElement(name = "TimedValue")

@XmlType(propOrder = {"value", "time"})

public class TimeValue {

  private String value = null;

  private Date time = null;

  @XmlElement(name = "value")  public String getValue() {

    return value;

  }

  @XmlElement(name = "time")  public Date getTime() {

    return time;

  }

}

The result is something like

<TimedValue>
  <value>hello</value>
  <time>2008-09-29T04:49:45</time>

</TimedValue>

Note that without the “propOrder” setting the ordering of elements is random due to unpredictable reflection.

Note, I never tried to compile the above, lol, it is just an example. The given names are also a match for the class information but could be named in any other way as long as the way is XML compliant. I prefer explicit naming for understanding and evolution.
