[Simple-support] Deserialization of type Calendar?

[Timo R. <cr...@ol...>]

Hello,

I can use Simple to serialize my model class, which holds a field of
type Calendar. But I'm unable to deserialize it, Simple produces this
Exception:

  --------------------------
  Exception in thread "main" org.simpleframework.xml.transform.TransformException: Transform of class java.util.Calendar not supported
          at org.simpleframework.xml.transform.PackageMatcher.matchUtility(PackageMatcher.java:184)
          at org.simpleframework.xml.transform.PackageMatcher.match(PackageMatcher.java:77)
          at org.simpleframework.xml.transform.DefaultMatcher.matchType(DefaultMatcher.java:111)
          at org.simpleframework.xml.transform.DefaultMatcher.match(DefaultMatcher.java:90)
          ...
          ...
  --------------------------


This is my simple test class that produces the exception:


  --------------------------
  public class CalendarSerializationTest {
    public CalendarSerializationTest() throws Exception {
  
      // Create test model
  
      CalendarSerializationTestModel model = new CalendarSerializationTestModel();
      model.setTime( Calendar.getInstance() );
                  
      ByteArrayOutputStream baos = new ByteArrayOutputStream();
  
      // Serialization

      // The method "SerializerFactory.getInstance( true )" just
      // creates a new Persister object with a cycle strategy

      Serializer serializer = SerializerFactory.getInstance( true );
      serializer.write( model, baos );
      String xml = baos.toString( "UTF-8" );
      System.out.println( xml );
                  
      // Deserialization
  
      CalendarSerializationTestModel modelDeserialized =
        serializer.read( CalendarSerializationTestModel.class, xml );
    }
  
    public static void main( String[] args ) throws Exception {
      new CalendarSerializationTest();
    }
  }
  --------------------------

  
The class CalendarSerializationTestModel is a very simple class:


  --------------------------
  @Root
  public class CalendarSerializationTestModel {
  
    @Element
    private Calendar time;
  
    // [...] Getter and setter methods for "time"
  }
  --------------------------

  
The test class produces this XML code:


  --------------------------
  <?xml version="1.0" encoding="UTF-8"?>
  <calendarSerializationTestModel xid="0">
      <time class="java.util.GregorianCalendar" xid="1">2008-10-01 14:59:43.109 CEST</time>
  </calendarSerializationTestModel>
  --------------------------

  
Am I doing anything wrong? What is the reason, that Simple is able to
serialize, but unable to deserialize the type Calendar?


Thanks a lot for your help!


Best regards,
