Some more info:
This is what I am doing, essentially.
msg = fromBTransport.receiveMessage(1000);
toBTransport.sendMessage(msg); |

It looks like the ArrayList contains one or more objects for which your forwarding application doesn't have the class files. The odd thing is that I think (without actually checking) that this should work if your app' just did
msg = QueueReceiver.receive();
QueueSender.send(msg);
Does your application actually try and get the content from the message?

ArrayList has objects of String class.
What may be the problem?

No idea. Perhaps you could post the stack trace from the JMSException, it might give me an idea for where to look. Am I correct in assuming that you get the exception from a call to ObjectMessage.getObject()?

getObject() gives the ArrayList and it could be read properly.
But when I do
msg = receiveMessage() from Q1
and = sendMessage(msg) from Q2
and I read the same message from Q2, I get UnserializableException.
thanks,
Shiva. |

Sounds vaguely reminiscent of an old bug. If you're not using the latest version of the classes (either those bundled with MQ5.3 or the latest MA88) then I'd try an upgrade. If you're already on the latest level then probably the best thing is to contact IBM support.
Cheers,
James. |
