Hai Everybody,Im having a funny problem with JMS Programs.
I have written two programs :one is 'WriteToQueue' which writes a msg to the queue and another is 'ReadFromQueue' which reads the message written into queue.ok this is working fine. But the problem is if I have written a msg without using the WriteToQueue program, that type of messages are unable to read by the 'ReadFromQueue' program while running the proagram(RFQ) it is throwing an Exception:java.io.EOFException.Thats it can I find a solution ,plz have a say on this. |

| It sounds to me like you are probably sending something other than TextMessages (MQ format of MQSTR) between the two programs. Can you give some more information on what type of message you are sending and what type of message you are receiving? Also, are you using a targetclient of JMS or MQ (ie, what about the RFH2 header on the messages)? |

If the reading program is JMS as he seems to imply there should be no RFH problem. It should read the message and the payload correctly whether the queue is defined with targetClient=1 or not. This is only effective when putting a message to the queue.
I think the problem might be an external program/utility putting messages to the queue in RAW format ==> bytes messages in JMS terms and the receiver program expects a TextMessage.
Another strong possibility is that the reader program uses a message selector checking for a specific condition in the RFH and the messages by the external tool would not have an RFH header hence the not found/EOF info.
Enjoy  |
