The file listener in that example is a gateway and used to get messages into an ESB bus. This gateway takes the content in the file and packages it in an ESB Message object. It then passes the Message object to the JMS listener, which a ESB-aware listener. anonymous wrote : Or is it mandatory? Well it has been, but there is a new feature in the main trunk for a in-vm transport where you don't need to configure the extra listener. Take a look at invm_transport1 for more details about this.
