RE: [castor-dev] How to suppress TimeZone offset when Marshalling java.util.date

[Jay Goldman]

I wrote specific handlers for date fields (actually i copied and modified an earlier post suggesting this approach)... such as:   public class DateOnlyDateHandler extends GeneralizedFieldHandler {     private static final String FORMAT = "yyyy-MM-dd";   private static SimpleDateFormat sFormatter = new SimpleDateFormat(FORMAT);   public DateOnlyDateHandler() {     }     public static String getFormat() {     return FORMAT;   }     public static SimpleDateFormat getFormatter() {     return new SimpleDateFormat(FORMAT);   }     /**    * This method is used to convert the value when the getValue method    * is called. The getValue method will obtain the actual field value    * from given 'parent' object. This convert method is then invoked    * with the field's value. The value returned from this    * method will be the actual value returned by getValue method.    *    * @param value the object value to convert after performing a get    * operation    * @return the converted value.    */   public Object convertUponGet(Object value) {     if (value == null) {       return null;     }     Date date = (Date) value;     synchronized (sFormatter) {       String result = sFormatter.format(date);       return result;     }   }     /**    * This method is used to convert the value when the setValue method    * is called. The setValue method will call this method to obtain    * the converted value. The converted value will then be used as    * the value to set for the field.    *    * @param value the object value to convert before performing a set    * operation    * @return the converted value.    */   public Object convertUponSet(Object value) {     Date date = null;     try {       synchronized (sFormatter) {         date = sFormatter.parse((String) value);       }     }     catch (ParseException px) {       throw new IllegalArgumentException(px.getMessage());     }     return date;   }     /**    * Returns the class type for the field that this GeneralizedFieldHandler    * converts to and from. This should be the type that is used in the    * object model.    *    * @return the class type of of the field    */   public Class getFieldType() {     return Date.class;   }     /**    * Creates a new instance of the object described by this field.    *    * @param parent The object for which the field is created    * @return A new instance of the field's value    * @throws IllegalStateException This field is a simple type and    *  cannot be instantiated    */   public Object newInstance(Object parent) throws IllegalStateException {     //-- Since it's marked as a string...just return null,     //-- it's not needed.     return null;   }   From: Stephen Burrows [mailto:[EMAIL PROTECTED] Sent: Friday, April 08, 2005 8:36 AM To: 'dev@castor.codehaus.org' Subject: [castor-dev] How to suppress TimeZone offset when Marshalling java.util.date   Hi All,   Does anyone know of a way to suppress timeZone offsets when marshalling a java.util.Date.   We unmarshall the following field   <dlx:FlightSegment DepartureDateTime="2005-06-04T11:45:00.000" ArrivalDateTime="2005-06-03T22:30:00.000+01:00" ResBookDesigCode="Y" RPH="0" FlightNumber="9566" NumberInParty="1">   Then marshall back and the castor marshaller adds the daylight saving timezone offset of +01:00 to the DepartureDateTime field.   <dlx:FlightSegment DepartureDateTime="2005-06-04T11:45:00.000+01:00" ArrivalDateTime="2005-06-03T22:30:00.000+01:00" ResBookDesigCode="Y" RPH="0" FlightNumber="9566" NumberInParty="1">   This causes problems when we pass messages between machines in different timezones , as the marshaller Adjusts the timezone accordingly and  changes the time   Example below > Request from time zone A: > <dlx:FlightSegment DepartureDateTime="2005-06-04T11:45:00.000+01:00" > ArrivalDateTime="2005-06-03T22:30:00.000+01:00" ResBookDesigCode="Y" > RPH="0" FlightNumber="9566" NumberInParty="1">   > Server Response from time zone B: > <ns2:FlightSegment DepartureDateTime="2005-06-04T20:45:00.000+10:00" > ArrivalDateTime="2005-06-04T07:30:00.000+10:00" ResBookDesigCode="Y" > RPH="0" FlightNumber="9566" NumberInParty="1">   DepartureDateTime has changed L   Any suggestions.?   Regards,   Stephen Burrows
