[castor-dev] Problem unmarshalling java.sql.Timestamp

[mothy.sundararajan]

Title: WELCOME to dev@castor.codehaus.org

 

 Hi,

 

In my project I am using the following in castor mapping xml file

 

  <field name="eventtime" type="java.sql.Timestamp"
   handler="org.exolab.castor.xml.handlers.SQLTimestampFieldHandler">

 

When I try to Marshal (write to xml file) the Timestamp field I have no problem, castor properly writes to xml file as follows

 

<eventtime>2005-08-09T03:22:48.107-04:00</eventtime>

 

But when I try to read this(Unmarshal) I am getting the following exception

 

java.lang.IllegalArgumentException: Type conversion error: could not set value o
f [EMAIL PROTECTED] with value of type java.util.Date

 I extended SQLTimestampFieldHandler and overriden convertUponSet to see how the Timestamp value is prased. The value printed in the console is Date format. While UnMarshalling castor by default marshalls it as Date. Is there any work around for this. I am using castor-0.9.7. As this is very critical for my project if anyone knows the answer please let me know.

 

import org.exolab.castor.xml.handlers.SQLTimestampFieldHandler;

public class ERSQLTimestampFieldHandler extends SQLTimestampFieldHandler{

 public ERSQLTimestampFieldHandler(){
  super();
 }

 public java.lang.Object convertUponSet(java.lang.Object value){
  System.out.println("convertUponSet >>" + value);
  return super.convertUponSet(value);

 }

}

 

Thanks
