Apache.NMS.WCF developers?
All -
I have a need to use the NMS WCF library in a current project, but need
support for Request Reply. As far as I can tell, the current library does
not support Request Reply
(http://stackoverflow.com/questions/2053631/duplex-or-request-reply-with-apache-activemq-wcf-binding-configuration-question).
I'm trying to understand how best to add this support. Are any of the
original WCF devs are still on the mailing list? Or if someone else has
enough WCF chops to help get me oriented.
Better yet, my company is willing to pay to get this done (and of course we
will contribute the resulting code back to the project). Any takers?
Thanks,
Steve

Hi, guys
My current project need to use Apache.NMS.WCF and I have encountered the
same issue, I debug into the source code of Apache.NMS.WCF,I can see the
message has been received by channellistener and call dispatch() to enqueue
the message but somehow it looks like doesn't hit in service layer. Does
anyone know how the channel layer interacting with the service layer? I
don't understand what supposed should happen after put the message in the
queue. And I was wondering any update of this issue? Thanks a lot.

A JIRA ticket might be a good way of handing it off. If it's a unit test,
that would be an excellent start to adding some unit tests to the WCF
provider.

Thanks! Yes, I'll send a test case - I'll need to clean up the code since
the driver program I'm using is a bastardized adaptation of a unit test we
used on a previous project with a different JMS implementation.
Where should I post the code? Should I open up a JIRA ticket and attach
there?

Thanks for the config. I'll take that and set it to my environment. Would
you mind sharing your sample code that you have so far to send the initial
message?

Its either that, or bitrot has set in and the code - which appears to be
almost 5 years old now. Perhaps it simply no longer works with modern
versions of .NET? Since I can't find any documentation, or examples or
unit tests I really don't know where to start. I scraped together a working
fire-and-forget client by using the config example from that stackoverflow
code and massaging it a bit. However that leaves me with a way to send
messages but not receive them.

Full disclosure on my side - I am a .NET developer, but I haven't used the
WCF bindings. :-)

there is some kind of configuration setting that is missing. It reads like
it is trying to enforce/protect the WCF communication model.

Well... Where do I start :)
Full disclosure: I'm a java developer trying to add support for our .NET
developers. I know just enough .NET to get myself into serious trouble.
The NMS.WCF source does not have any example or test projects - and no
documentation that I've been able to find. The stackoverflow article I
linked to does have an App.config excerpt that I've been able to adapt to
get some semi-working code.
I've built the NMS libs from source and have used them to create a simple
one-way "fire and forget" message onto a queue via the WCF library. So far
so good.
When it comes to creating a service to listen to that queue and does
something with it, however, I get runtime exceptions. At this point in
NmsInputChannelListener.cs:
NmsInputChannel newChannel;
bool channelCreated = CreateOrRetrieveChannel(out newChannel);
Tracer.Debug("Dispatching incoming message");
>>>>> newChannel.Dispatch(message);
I get an exception complaining that the channel is in Created state and
needs to be in Open state. I've stepped through the
CreateOrRetrieveChannel() function and indeed - it creates a new channel,
but does not open it. Might I be missing something in my App.config? Is
there a test project I've not discovered that tests this code -- (i.e can I
confirm that the WCF library itself still works and that it is my client
code that is at fault?)
Once I get past these very basics, I will probably be able to articulate
more specific Request Reply questions.
DEBUG: Dispatching incoming message
ERROR: Error dispatching Message: System.InvalidOperationException: The
communication object, Apache.NMS.WCF.NmsInputChannel, is in the Created
state. Communication objects cannot be used for communication unless they
are in the Opened state.

Hi Steve,
I read the reply from marc_s on that Stack Overflow link you provided.
What is missing from his answer that you are needing? It seems like he
covered the solution necessary for implementing request reply, or am I
missing something different in your requirements?
Best,
Jim
