Best way to pass information between two message mappings

[Former Member]

Hi,

I'm using two chained message mapppings (one after another in the operation mapping / interface mapping).

How could I pass information from the first message mapping (graphical or Java, I don't mind) to the next one without modifying the payload?

I'm thinking if it could be possible to set some custom header parameters in the header of the message, but I think that only works in adapter module development.

Thanks!

Hi Jorge,

Try this...

UDF in first Message Mapping - setDynamicVariable(String name, String value)

DynamicConfiguration dc = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);

if (dc == null)
   return "Works with Interface Mapping test only.  Not Message Mapping test.";
	
DynamicConfigurationKey key = DynamicConfigurationKey.create( "http://my.test.com/custom", name);
dc.put(key, value);

return value;

UDF in second Message Mapping: getDynamicVariable(String name)

DynamicConfiguration dc = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);

if (dc == null)
   return "Works with Interface Mapping only.  Not Message Mapping.";
	
DynamicConfigurationKey key = DynamicConfigurationKey.create( "http://my.test.com/custom", name);
return dc.get(key);

Thanks,

Hi Russel,

I think that's the way to go. I thought that the dynamic configuration section of the XI message was reserved for setting adapter specific attributes, and so I discarded it.

I'll try and let you know.

Lopez,

I think your question is incomplete. If I understand correctly you have two message mappings for example and for mapping1 output should be the input of mapping2. If yes then simply take the target of mapping1 and give it as source1 of mapping2. Please see this help for more information:

He is doing xsl mapping in his example. In your case change your mapping accordingly.
