I am running WMB 6.1
I did some research and came across the following two posts on this forum:
http://www.mqseries.net/phpBB2/viewtopic.php?t=34633&highlight=localenvironment+message+mapping+node
...and
http://www.mqseries.net/phpBB2/viewtopic.php?t=34940&highlight=localenvironment+message+mapping+node
but no joy, didn't give me the answer I need.
I am using a Mapping Node to map one WSDL to another. Before I get to the Mapping node, I store my MQMD to the LocalEnvironment:
| Quote: |
| SET OutputLocalEnvironment.MySavedMQMD = InputRoot.MQMD; |
The Mapping Node is configure to the following: Mapping Mode: LocalEnvironment And Message.
But when I pass the Mapping Node my LocalEnvironment tree is empty.
I'm not sure what I don't understand because the documentation states that with this setting the LocalEnvironment should survive:
| Quote: |
| The LocalEnvironment tree structure and message are generated or passed through by the Mapping node, as modified by the node. |
so... is there something I need to set within my mappings or am I missing something else? |

Please try with environment variable and see, if the MQMD is populating at first.
then reinitialize on to LocalEnvironment

In Mapping Node configuration use 'Message' instead of LocalEnvironment And Message.
Thanks

Gemz,
Can you explain the reason for your advise?
By changing the mode as you suggested any changes to the LocalEnvironment are lost.

Hi shalabh
Can you please let me know how you are changing or accessing the LocalEnvironment Variables in mapping node.?
Regards

Gemz,
I'm a bit surprised that it worked, but thanks a lot for your assistance.
I guess I have the same question that shalabh1976 posed. Will keep a tab on this post to see what comes from it.
Thank you to all that replied to my question, I appreciate it a lot!

That is telling the Broker that you will build both the LocalEnvironment and the Message inside the node.
The only trees that are passed, unchanged, from Input to Output are the ones not listed in the Property.
Cheers,

EddieA,
Now that makes a lot of sense!
A bit confusing I'd say (or is it just me...  ), but when you set a Compute Node to be 'LocalEnvironment And Message', then the variables are available further down the flow, but the Mapping Node works the other way around. And both of them does the same thing (in principle). I think that's where I got my nuts in a knot.
Won't easily forget this one... thanks for all the input and assistance!

Actually, it really works the same way.
If you use a compute node, and set the Compute mode to 'LocalEnvironment and Message' and then do not copy InputLocalEnvironment to OutputLocalEnvironment... then LocalEnvironment is not available further down the flow...
Most people, however, always call either CopyEntireMessage() or CopyMessageHeaders() (and, please, never add code to these functions!), which copies InputLocalEnvironment...
