Hi Amila,
Your understanding is correct, and the operation element is expected to
add an operation to the service at the module engagement time.
What is the axis2 version that you are trying? This works on the trunk
as well as most of the recent releases of axis2 and WSO2 based products,
so it is hard to assume this as a bug on the axis2 or caching code. Have
you deployed the module correctly and engaged it.
Thanks,
Ruwan

Hi Devs,
What exactly expected from putting the <operation> block in a
module.xml file? Does it add that operation to the services when the
module get engaged?
For example the module.xml of the caching module contains the
following block,
<operation name="CachedOperation"
mep="http://www.w3.org/2006/01/wsdl/in-out";>
<messageReceiver
class="org.wso2.caching.receivers.CachedMessageReceiver"/>
</operation>
Then in the CachingInHandler it tries to access this operation from
this code,
AxisOperation cachedOperation =
axisService.getOperation(CachingConstants.CACHED_OPERATION_QNAME);
where CACHED_OPERATION_QNAME = "CachedOperation"
I have moved the carbon\caching module to Axis2 and when I was
debugging it can not find an operation with name "CachedOperation".
Then I checked the axisService.operationsAliasesMap it also does not
contain the "cachedOperation".
What may be the reason for this operation not being present in a service?
Thanks,
Amila
