Hi All,
We are using Websphere ver 6.1 and MQ ver 6. After writing an ObjectMessage to a queue, the clients receive it as a BytesMessage. There are two different environments that one of them works fine with the same code and the other one makes this problem. I compared all the qcf and queue definitions between the two environments but everything is exactly the same.
Have you ever faced a problem like?
Thanks in advance. |

Using an Object Message is dubious. Unmarshall the object and send it as text.

I doubt very much that both environments are the same.
What does the targetClient attribute say on the destinations?
If you have to deal with a BytesMessage and you KNOW that it should be an ObjectMessage you can allways try to put the bytes into a ByteArray and use the IO stream and buffer classes to get an ObjectInputStream from which to unmarshall your objects...
But the ideal solution is, as my esteemed colleague pointed out, to transform the object into XML and not use object messages. (One version of Java might have different marshalling properties as the other and you might not always be able to unmarshall the object...)
Have fun

Thank you very much for your replies.
Unfortunately, we cannot do anything for the way that objects are sent to (or received from) the queues. There is a framework that everyone is using in this organization. So, I suppose either there is something with the versions/patches of our Websphere and/or MQ, or that, the queues are not defined exactly like what we used to have in the previous environments.
I will keep you updated as soon as I get to a conclusion.
Thanks again. |
