Routes

Integration flows (scenarios) are organized in routes. Every route has 1 FROM and 1...n TOs.

                                    XML DSL:

                        <from uri="ftp:server/folder"/>
                        <to uri="activemq:queue:orders"/>
                                    

                                    Java DSL:

                       from("ftp:server/folder")
                       .to("activemq:queue:orders");
                                    

Routes

Simply said: Route is a path followed by the message.
