I wanted to understand how can I use Web sphere MQ for the following scenario:
1.How I can read the message from the queue without removing that message from the queue.
2. We have a web application so we need the Listener to read the Queue. Is there any tool to do this ?

Answer 1

Yes, it's possible to read message without removing from a queue, it's known as Browsing. You will need to create a browser consumer to read the messages. I have posted snippet here, same code is available in Tools\dotnet\samples\cs\xms\simple\wmq\SimpleQueueBrowser\SimpleQueueBrowser.cs also.
// Create connection.
IConnection connectionWMQ = cf.CreateConnection();
// Create session
ISession sessionWMQ = connectionWMQ.CreateSession(false, AcknowledgeMode.AutoAcknowledge);
// Create destination
IDestination destination = sessionWMQ.CreateQueue(queueName);
// Create consumer
IQueueBrowser queueBrowser = sessionWMQ.CreateBrowser(destination);
// Create message listener and assign it to consumer
MessageListener messageListener = new MessageListener(OnMessageCallback);
queueBrowser.MessageListener = messageListener;
// Start the connection to receive messages.
connectionWMQ.Start();
Callback method
static void OnMessageCallback(IMessage message)
{
try
{
// Display received message
Console.Write(message);
}
catch (Exception ex)
{
Console.WriteLine("Exception caught in OnMessageCallback: {0}", ex);
}
}
