Simple java code in graphical mapping - XI

[MichalKrawczyk]

This Weblog presents two things:

1) the use of trace

2) the use of Technical Context Objects



in the message mappings.




1. There are times (like debugging) when you want to add a trace to your message mapping.
No problem, you can do it quite easily by adding some code in your user defined function:

MappingTrace importanttrace;

importanttrace = container.getTrace();

importanttrace.addWarning("The value of the tag is:" + variable);

Value of the tag is: 123456






for traces that can be written to the Trace
please take a look at section

"Trace Level of the Pipeline and Mapping Trace" on page:

2. You can also easily get the names of the Technical Context Objects (like MESSAGE_ID or INTERFACE_NAMESPACE)




<p>String constant;java.util.Map map;map = container.getTransformationParameters();constant = (String) map.get(StreamTransformationConstants.INTERFACE_NAMESPACE); return constant;</p>



a list of the Technical Context Objects names can be found here:

*************************Remember*************************

You can't see the Technical Context Objects
like MESSAGE_ID
when you're testing your mapping in the XI Repository.
You can only see this in message monitoring
when you post a message.
