And the corresponding fields in the MQMD are defined as ?
Did you make sure you defined the Calendar in the GMT time zone?

Have fun

In MQMD PutDate and PutTime fields are defined as java.util.GregorianCalendar. In restoring ,converted String date/time to java.util.GregorianCalendar set to PutDate/time.

Yes,Calendar in the GMT time zone.

I don't think so. I did not ask you what was returned from Java.
If you look at the MQMD C definition, what are the fields defined as?
String 6?, string 8?
What do they show up as if you look at them with rfhutil?
You may have to define a SimpleDateFormat in the GMT time zone to write the date/time out to the field...
Now if you can ensure that you have the MQMD parser as a field parser you may keep using a Date and maybe Time class... / Calendar class...

As per MQMD C definition field defined for PutDate as MQCHAR8.

We have tried SimpleDateFormat in the GMT time zone.JVM has thrown 'invalid type name value' exception.

For PutDate, set java.util.Date type in JCN. Got 'invalid type name value' exception at this statement.

Tried with GregorianCalender() as well.Got same exception.

Stop trying to use Java date types. Lookup what characters the MQMQ is expecting in those fields and in what order. I would bet it is not the same as a Java type.

And show your code. Otherwise we are all guessing at what you are really doing.

Hi ,
We are trying following java code to set the putDate and putTime.
Code:

try {

SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd");
SimpleDateFormat timeFormat = new SimpleDateFormat("HH:mm:ss.SSS");

Date putDate = dateFormat.parse(MBMessageUtils.getElementValue(mqmdHeader,
"PutDate", false, false));

Date putTime = timeFormat.parse(MBMessageUtils.getElementValue(mqmdHeader,
"PutTime", false, false));
GregorianCalendar calender = new GregorianCalendar();
GregorianCalendar calender1 = new GregorianCalendar();
calender.setTime(putDate);
Object cal = calender;
calender1.setTime(putTime);
String puttimefinal = timeFormat.format(putTime);
// mqmdHeaderElement.createElementAsLastChild(MbElement.TYPE_NAME_VALUE,
// "PutDate",calender);
mqmdHeaderElement.createElementAsLastChild(MbElement.TYPE_NAME_VALUE,
"PutDate",cal);

//
mqmdHeaderElement.createElementAsLastChild(MbElement.TYPE_NAME_VALUE,
"PutTime",calender1);
} catch (ParseException e) {
}


Got following exception.

Code:

Function:CHARACTER:setValue
Type:CHARACTER:
Name:CHARACTER:
Label:CHARACTER:
Catalog:CHARACTER:BIPmsgs
Severity:INTEGER:3
Number:INTEGER:4373
Text:CHARACTER:Invalid element value type
Insert
Type:INTEGER:5
Text:CHARACTER:java.util.GregorianCalendar

I am not sure the date and time format match.
On the other hand I don't believe that the return form when you read the field on a message would be a Calendar object. More like a Date object perhaps?

So you could try setting the value by passing a Date object, or get the format right and set the text value.

Have fun

Check out the IIB Java user-defined extensions API. For MbElement.createElementAsLastChild(), the value Object must be one of the following types:
  • MbDate
  • MbTime
  • MbTimestamp
  • Boolean
  • byte[]
  • String
  • Integer
  • Double
  • BitSet
