C# NMS client
Hi, I'm attempting to write an NMS C# client. I just want to get a simple
example client going. I have done the following:
1) downloaded C# code from:
https://svn.apache.org/repos/asf/incubator/activemq/activemq-dotnet/trunk/src/main/csharp/NMS/
2) placed above files (*.cs) in a project and built an NMS dll, which builds
fine
3) have created a 2nd VSCS project to test the NMS, which references
NMS.dll. It includes the code from here:
http://www.activemq.org/site/nms.html, which is also shown below.
4) Question, when I try to build the code in 3) above (and shown below), I
get an error..."ConnectionFactory" is not defined. Where is it defined? I
noticed IConnectionFactory is abstract...so somwhere it must be defined?
Thanks, MikeyBoy
------code from http://www.activemq.org/site/nms.html:
IConnectionFactory factory = new ConnectionFactory(new
Uri("tcp://localhost:61616"));
using (IConnection connection = factory.CreateConnection())
{
Console.WriteLine("Created a connection!");
ISession session = connection.CreateSession();
IDestination destination = session.GetQueue("FOO.BAR");
Console.WriteLine("Using destination: " + destination);
// lets create a consumer and producer
IMessageConsumer consumer = session.CreateConsumer(destination);
IMessageProducer producer = session.CreateProducer(destination);
producer.Persistent = true;
// lets send a message
ITextMessage request = session.CreateTextMessage("Hello World!");
request.NMSCorrelationID = "abc";
request.Properties["JMSXGroupID"] = "cheese";
request.Properties["myHeader"] = "James";
producer.Send(request);
// lets consume a message
ActiveMQTextMessage message = (ActiveMQTextMessage) consumer.Receive();
if (message == null)
{
Console.WriteLine("No message received!");
}
else
{
Console.WriteLine("Received message with ID: " +
message.NMSMessageId);
Console.WriteLine("Received message with text: " + message.Text);
}
}

Thanks James for the information. I was able to build activemq-dotnet.dll and
built a small test application. I fixed the problems with the 2 missing
files (ConnectionControlMarshaller.cs and ConsumerControlMarshaller.cs). If
anyone is interested they can download it from below. This is a zip file
which contains an activemq-dotnet project (which crates the dll) and a
project called TestNMS which tests a consumer and producer and includes a
reference to the activemq-dotnet.dll file. Download here:
http://www.olsendarter.org/dev/activemq-dotnet.zip
Also, you must download NUnit and install it as it is included as a
reference. See :
http://www.nunit.org/
I hope this saves someone some time.

There's currently no DLL to download (unfortunately we're still
waiting for the maven csharp plugin to be fixed) - but you can build
it yourself using NAnt as described here...

Hi Rob, forgive my ignorance, I'm just starting out with ActiveMQ. I am
puzzled where the activemq-dotnet.dll file you mentioned comes from. I built
my own NMS.dll file using MSVS using just the NMS source, which does not
contain any ActiveMQ namespace. Do I also need to build activemq-dotnet.dll?
Are the DLLs available for download anywhere? I'm missing something
here...TIA, M

I like the fact they're now separate. It makes the whole C# client much

Good point - I guess they should stay separate.

Yeah, good idea.
It'd be good if windows/.net folks could just add ActiveMQ.DLL for
using ActiveMQ and NMS-MSMQ.DLL for accessing MSMQ maybe? I wonder if
it'd be nice to include the NMS API inside the 2 DLLs?

Hi James,
That sounded like such a good idea that I started working on it.
Before I get too far into it, I'm starting to realize that it would be
a bad idea if I just dumped an implementation for MSMQ into the
current code base since then the code would probably not compile or be
testable on non-windows platforms. Would this be a problem?
If we do go with breaking this out to separate module, I think the NMS
name space should be it's own module too.

Hopefully someone could write an MSMQ implementation of NMS too; then
folks could switch between various messaging providers using the same
NMS API.

The reason for the 2 namespaces is that the interfaces in NMS name
space can be implemented by other messaging systems and is not
ActiveMQ specific.
The ActiveMQ namespace has our implementation of the interfaces in the
NMS namespace. If you use an object factory that creates the initial
ConnectionFactory for you, then your application code can stay
decoupled from ActiveMQ since it only needs to use the interfaces in
the NMS namespace. But that can be a little tricky to setup, so most
folks just import the ConnectionFactory from activemq namespace
directly.

Hi Mike
No, the activemq-dotnet DLL contains two top-level namespaces: NMS and
ActiveMQ; I'm not sure of the rationale for this. If you view the DLL in
VS.Net object browser you'll see all the namespaces it contains.
You simply need to reference the DLL (which you're already doing I believe)
and include the line:
using ActiveMQ;
in your source.
Hope this helps

Hi Rob that's for the reply. Somehow I assumed NMS could be used as a
stand-alone client. I looked at the ActiveMQ Windows binary and see it
contains no DLLs, just JARs. So do I need to build an ActiveMQ DLL callable
from .net? TIA, M
