Hi all,

I have a flow that is reading XML messages from an MQ Queue as the entry point of the flow.
I have the following configuration:
- MQ Server has the character set (CCSID) set to 819, which corresponds to ISO- 8859-1 codification that supports Spanish characters.
- My MQInput node has XMLNSC as the Input Message Parser, and the "Convert" checkbox is not selected in the Advanced tab.

When testing the flow in IIB v9 with the "Test Message Flow" option, I'm pasting this XML with a string containing an accent:

<?xml version="1.0" encoding="ISO-8859-1"?>
<FullProject>
<Title>Integracin</Title>
</FullProject>

When the flow stops after the MQInput node, this is what "Title" element has:
Title:CHARACTER:Integración

Which is the error or configuration problem I am doing?

Thanks for your help

Check the bytes of your input message. What byte value is being sent for the accented character?

Hi Timber,

Thanks for your answer. How can I check the bytes sent of my message? I'm quite new in the usage of MQInput node in IIB.

Thank you

Look at the message on the queue.

Ensure your queue browsing tool is not converting the data.

Or unload it to a file with MO71, or qload (dmpmqmsg) and look at the hex.

Hi,

Right, the message is already bad formatted in the queue. I guess the problem is located then in the "Test Message Flow" utility of IIB.

Am i missing some special configuration regarding character encoding in this utility?

Thanks a lot for your help

IMHO it's more likely the rather simplistic Toolkit function isn't up to the task of testing your flow. Remember it's basically an Eclipse plugin running on Windows.

You might be able to do something changing the settings on the Windows OS, but if I was in your position I'd add a correctly formatted / encoded message to the input queue with qload (or equivalent utility of your choice) and test the flow that way.

Hi Vitor,

Yes, you are right, I'll test this feature sending the messages directly to the queue rather than using this Toolkit Functionality.

Thanks a lot

Don't forget you can still use the Toolkit debugger (urgh) even if you add the message manually.

Also don't forget the debugger is really terrible with CCSID problems (for the same sort of reasons you've found) and a user trace is going to be a better bet for problem solving messages with exotic content.
