Problems with custom xsd:dateTime conversion

[aravind yarram]

Hi All,

I want to use custom written conversion utility to convert the date time genrated from the default implementation. So, I have written the following custom conversion class

Error

DefaultValidationEventHandler: [ERROR]: Cannot format given Object as a Date
Location: obj: com.aravind.customdatetime.impl.CustomDateTypeImpl@7ff8e19c
javax.xml.bind.ValidationException
- with linked exception:
[com.sun.xml.bind.serializer.AbortSerializationException: Cannot format given Object as a Date]

 
import java.text.DateFormat;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;
 
public class DateConversionUtility 
{
 
static final SimpleDateFormat onlyDate = new SimpleDateFormat("yyyy-MM-dd");
static final SimpleDateFormat dateAndTime=new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");

public static String printCalendar(Calendar c) 
{
return onlyDate.format(c.getTime());
}
 
public static Calendar parseCalendar(String c) throws ParseException 
{
Date d = onlyDate.parse(c);
Calendar cal = Calendar.getInstance();
cal.setTime(d);

return cal;
}


public static String printDateTime(Calendar d) throws ParseException
{

String s=dateAndTime.format(d);
 
return s;
}

public static Calendar parseDateTime(String dt) throws ParseException
{

dateAndTime.setLenient(false);
Date date = (Date)dateAndTime.parse(dt);
Calendar cal = Calendar.getInstance();
cal.setTime(date);

return Calendar.getInstance();
}
}
 

Here is the custom bindings file

 
<?xml version="1.0" encoding="UTF-8"?>
<jxb:bindings version="1.0"
               xmlns:jxb="http://java.sun.com/xml/ns/jaxb"

    enableFailFastCheck="false"   
    generateIsSetMethod="false"
    underscoreBinding="asCharInWord">

    </jxb:javaType>
    
    </jxb:globalBindings>
 
</jxb:bindings>
</jxb:bindings>

However, when i try to Marsahll I am getting the following exception, I am not sure why though. I'd be very thankful if you can help me fix this issue

 
import java.util.Calendar;
import javax.xml.bind.JAXBContext;
import javax.xml.bind.JAXBException;
import javax.xml.bind.Marshaller;
import javax.xml.bind.Validator;

public class CustomDateTime {
 
public static void main(String[] args) {
try
{
JAXBContext ctx=JAXBContext.newInstance("com.aravind.customdatetime");

//Create the content tree
ObjectFactory objF= new ObjectFactory();
 
CustomDateType dt=objF.createCustomDateType(Calendar.getInstance());
//dt.setValue(Calendar.getInstance());


//Validate On Demand
Validator v=ctx.createValidator();
boolean valid=v.validateRoot(dt);
System.out.println(valid);

//Marshall the Content Tree
Marshaller m=ctx.createMarshaller();
m.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT,Boolean.TRUE);
m.marshal(dt,System.out);
}
catch(JAXBException e)
{
System.out.println(e);
}
}
}
