Hi, Ignacio.
I have made some progress here with the following changes.
1) In the implementation.notification provider, set the default databinding
of the service implementation contract to OMElement.
2) Add wstx-asl-3.2.1 and tuscany-databinding-axiom as untime dependencies
Now I'm at the point that your help is needed. Can you explain the following
code in
org.apache.tuscany.sca.binding.notification.NotificationBindingProviderFactory?
Please note now we defer the activation of references to the 1st time they
are used for invocation. So the assumption of that all references/services
are pre-activated are NOT true any more.
Thanks,
Raymond

Subject: [jira] Commented: (TUSCANY-1620) Exception running the
binding-notification-producer sample

Ignacio Silva-Lepe commented on TUSCANY-1620:
---------------------------------------------
I misspoke above about where the databinding interceptor is not being
added. The trace above shows the invocation chain between the notification
component and the composite reference. In particular, it shows the
notification component invoker calling the notification reference binding
invoker directly with no databinding interceptor in between. This is
indeed correct, as both ends have the same databinding.
However, where a databinding interceptor _should_ be added is in the
invocation chain between the traffic advisory producer and the
notification component.
Doing a little bit of debugging, I have a break point in
DataBindingRuntimeWireProcessor.process, and in line 116 I can see that
the target contract (a WSDLInterfaceContractImpl) has a single
OperationImpl in its list of operations, which is ok, but this operation
has a dataBinding value of null. This means that isTransformationRequired
eventually returns null and no databinding interceptor is added.
I am not sure what has changed in the last week or so to make this happen,
as I am assuming that the OperationImpl's databinding value was not null
before, since the sample was working.
Any ideas?
Exception running the binding-notification-producer sample
----------------------------------------------------------
Key: TUSCANY-1620
URL: https://issues.apache.org/jira/browse/TUSCANY-1620
Project: Tuscany
Issue Type: Bug
Components: Java SCA Data Binding Runtime, Java SCA Samples
Affects Versions: Java-SCA-0.99, Java-SCA-1.0
Environment: WIndows XP
Reporter: Ignacio Silva-Lepe
Fix For: Java-SCA-0.99, Java-SCA-1.0
I am getting the following exception trying to run the
binding-notification-
producer sample and trying to send a message to a binding-notification-
consumer. The NotificaitonReferenceBindingInvoker is expecting an
OMElement that should be coming from the notification component via
the corresponding databinding. But I don't see a databinding interceptor
between the RuntimeSCABindingInvoker and the NotificationReference-
BindingInvoker, the way you see it in the databinding-echo trace of
TUSCANY-1582.
Any ideas as to why the databinding interceptor is not being added to the
invocation chain?
