ActiveMQ and Tibco provides interoperability with C# client throw Spring.NET Messaging APIs. I tried ActiveMQ and it worked just fine. The code looked like this: ActiveMQ.ConnectionFactory factory = new ConnectionFactory("tcp://localhost:61616"); connection = (Connection)factory.CreateConnection(); session = (Session) connection.CreateSession (NMS.AcknowledgementMode.AutoAcknowledge); topic = session.GetTopic("topictest.messages"); publisher = session.CreateProducer(topic); IMessageConsumer consumer =session.CreateConsumer(topic); consumer.Listener+=new MessageListener(consumer_Listener); I managed to produce jboss-messaging-client.dll using ikvmc... Everything should work with C# once I manage to get connection to the broker... I cant find ConnectionFactory in the jboss-messaging-client APIs and I dont know how to use JDNI in C# if that is possible. How can I over come this?
