how to read a EBCDIC message from a main-frame ? ....when I print the message (bytesMessage) object its showing ..CCSID of 500.
while creating queue object ....am using the sting as following
| Code: |
queue = queueSession.createQueue("queue://HOST1.QM1/"+queueName+"?persistence=1&priority=5"&CCSID=1208&encoding=273);
queueReceiver = queueSession.createReceiver(queue) ;
Message msg = queueReceiver.receiver() ;
System.out.println("message object "+msg); |
Am still seeing the bytes message ... I was expecting message to get converted to 1208 (UTF8) so that its in readable format ...but its not ..
will someone tell me ...what's wrong is happening in the above code ? quick help ..tip would be greatly appreciated ....
thanks

Hi,
The EBCDIC has to be converted into ASCII in the MainFrame,
Once it is done u can receive the message as 'bytesMessage'.
U need to use an Exit Routine for the conversion or some other way.
And u can't specify the CCSID=1208,
Here r the different values u can speciy, if u r reading a message from Queue Manger on
windowsNT = 819
Unix = 819
The QM will handle conversion to its format (btn diff OS).
Basically avoid specifying the CCSID and Encoding in the Queue Object.
Just take care of conversion above mentioned. And u should be able to read the messages in bytesMessage.
Here i have a question (since info u provided isn't clear..)?
r u using JMS application to read message directly from a MainFrame Queue? (have u succeded in doing so..)
thanks

yes youre right ..am using jms to read the message directly from the main frame queue.
And changing the definition of the queue isnt possible. All trick / manipulation have to done at jms coding level.
dont tell me that am still not clear 
as always .. any quick help, tip is appreciated ..
thanks

Hi,
If u r using JMS directly to read from a MainFrame Queue,
and
creating a Queue Object instace the following way
queue = queueSession.createQueue("queue://HOST1.QM1/"+queueName+"?persistence=1&priority=5"&CCSID=1208&encoding=273);
It will not work, as there won't be any message with CCSID=1208 in Main Frame Queues.
Because UTF-8 format is not supported by MQ on MainFrame. And ur JMS application doesn't handle the format conversion. It just maps between different JMS message formats. Thats the basic reason u r not able to read the messages.
As i told u in the earlier response, after handling the EBCDIC - ASCII conversion, if u use the JMS to read the message(ASCII), as 'bytesMessage' u will get the message. If u call 'toString' on bytesMessage it will return u the 'UTF-8' string format.
thanks
