Betreff: Re: warnings using callbacks

Hi Martin
Hi Simon,
WARNUNG: Reference not found for component reference: Component =
UpdateServiceImplComp Reference = UpdateRegistry
Means that there is a reference in a composite whose name doesn't
match a reference in the component implementation. This is
missleading
here though I think because it's complaining about the automatically
created callback reference that takes the name of the service for
which it is the callback reference. Please raise a JIRA for this.
This works OK in other examples, so I have a suspicion that the
problem is associated with using the domain manager to start the node.
My guess is that the domain manager is adding an extra reference
to the runtime composite that it sends to the node. The domain manager
should not do this, but should leave it to the node to create the
extra reference representing the callback. We can look into this
as part of the JIRA investigation.
In addition:
For the clients I got the warnings
WARNUNG: Service not found for component service: Component =
UpdateListenerImplCompHostA Service = updateRegistry
WARNUNG: Skipping component service not defined in the component type:
UpdateListenerImplCompHostA#updateRegistry
I guess this is the counterpart for the above warning.
If necessary how can I open a JIRA ?
Martin,
Are you able to try this with the newest 1.5 release of Tuscany?
I have been running similar application code on this level of Tuscany
without seeing any of these problems. It is possible that this may be
a problem that has already been fixed.

WARNUNG: Multiple bindings with the same name for a service: Binding
=
UpdateRegistry Service =UpdateRegistry Binding = {2}
Means there are multiple bindings with no name on the service
"UpdateRegistry". Again this is a little strange. I don't know why it
would be adding another binding in this case. The error message is
also very strange. Can you add this to the JIRA also and we'll take a
look at it.
The service has a forward <binding.ws/> and a callback <binding.ws/>.
These have no "name=" attribute, so they both default to the name of
the service. SCA doesn't permit two bindings with the same name, and
this is why you get the warning. The {2} in the message is a bug in
the 1.3.1 message template, and has been fixed in the latest code.
Tuscany is doing the right thing by producing the warning. The
solution
is to change the service callback binding to something like
<binding.ws name="UpdateRegistryCallback"/>.
After doing so I got the warning
WARNUNG: Multiple bindings with the same name for a reference: Binding =
updateRegistry Reference = updateRegistry Binding = {2}
so I did the same for the callback binding of the reference
and the warnings disappeared.
Thanks.
Simon N.
