Why do these intents with the same name have to be the same instance? We 
could have four instances and have each of them point to the corresponding 
operation.

If I understand correctly, you're trying to reference (instead of 
instantiate) the intents by QName to the ones defined in definitions.xml. 
Conceptually, I treat these two as different things:

Intent type ...................... <intent name="tuscany:logging> from 
definitions.xml (Defining an intent type)
Intent configuration .......... requires="tuscany:logging" from the 
composite file (An intent whose type is tuscany:logging)

Thanks,
Raymond

Hi,

I went ahead and tried to implement this thinking thro some scenarios
along.  Here is one that seemed to have a problem with this approach. 
Take
the composite...

<composite...
<component name="CalculatorServiceComponent">
       <implementation.java class="calculator.CalculatorServiceImpl">
           <operation name="add" requires="tuscany:logging"/>
           <operation name="subtract" requires="tuscany:logging"/>
       </implementation.java>
</component

<component name="AnotherCalculatorServiceComponent">
       <implementation.java class="calculator.CalculatorServiceImpl">
           <operation name="multiply" requires="tuscany:logging"/>
           <operation name="divide" requires="tuscany:logging"/>
       </implementation.java>
</component
</composite>

While processing 'CalculatorServiceComponent' the add and subtract
operations will be added to the logging Intent.  While processing the
'AnotherCalculatorServiceComponent' the multiply and divide oeprations 
will
be added to the logging intent.  Since there is one instance of the 
logging
intent that is shared by these two components, it ends up that the logging
intent gets to apply for all four methods in both components, which is not
what is intended.

Thoughts ?

Thanks

- Venkat
