I didn't have the exact code I am using ,so I can only explain the pseudo code further :
//I set up the objects which is necessary to send msgs in the beginning of the program IConnectionFactory f1 = new ConnectionFactory("some url"); IConnection c1 = f1.CreateConnection(); ISession s1 = c1.CreateSession(AcknowledgementMode.Transactional); ITopic topic = Apache.NMS.Command.Topic("Testing Topic"); ........somewhere else in the code .......... //I create 10 producers to send messages concurrently , as you can see //they are created from the same session. The session is set to transactional mode. for(int i=0;i<10;i++)// { IMessageProducer prod = s1.CreateProducer(destination); System.Threading.Thread t = new Thread(SendMessage); t.Start(prod); } private void SendMessage(object data) { IMessageProducer prod = (IMessageProducer)data; //........I create a BytesMessage ......... for(int i = 0 ;i<10000 ; i++) prod.send(............)//I send Message persistently , I didn't type out all the params in send method s1.commit();//commit the transaction } HellKnight wrote > I am using activemq 5.8.0 , jdk 1.7 , c# NMS (.NET 4.0). > I write a producer and a consumer program for testing purpose.
