Messaging Transports

A transport is a queueing or communication mechanism that Jasper knows how to use to both deliver and receive messages to and from other systems. The transport can take care of mapping your message objects and the Jasper Envelope to each transport's particular usage. Using Jasper should mostly make the choice of underlying transport be opaque to your application code (except for the bootstrapping of course). That being said though, Jasper tries to enable as much of the advanced usage of your underlying transport as possible.

Configuring Listener or Sending Endpoints

All of the transport types can be configured by using meaningful Uri values specific to each transport type. You'll probably find it easier to use the specific configuration helpers for each transport type, but let's look at the generic Uri configuration mechanism first.

All listener or sender endpoints are registered from the JasperOptions.Endpoints property like this:


public class SenderAndListener : JasperOptions
{
    public SenderAndListener()
    {
        // All messages get published via TCP
        // to port 5555 on the local box
        Endpoints
            .PublishAllMessages()
            .To("tcp://localhost:5555");


        // Listen for incoming messages at
        // port 6666
        Endpoints
            .ListenForMessagesFrom("tcp://localhost:6666");
    }
}

It is important to note that all of the transport endpoint types can be used in either a lightweight fire and forget with limited retries, or with durable, store and forward messaging or guaranteed delivery. For durable messaging.
