Notification Producer Binding Sample =============================== This sample illustrates the use of with a remote producer. The README in the samples directory (the directory above this) provides general instructions about building and running samples. Take a look there first. Sample Overview --------------- This sample illustrates the use of a notification producer that is located in a separate (and remote) composite with respect to any consumers. As such, this sample is run in conjunction with the binding-notification-consumer sample, the binding-notification-broker sample, or both. Take a look at the composite file or the .svg file which shows the composite file in pictorial form. The composite reference, referred to by the notification component, has a that handles the remote communication. This binding includes an 'ntm' attribute that refers to the notification type manager, which manages the connectivity of producers, consumers and brokers, and which (for this sample) is assumed to be running on http://localhost:8083. The ntm is a system component that is included in and runs as part of the binding-notification module. This sample also illustrates the use of a wsdl interface in the notification component's . This allows messages sent and received via to be transported as literal xml over http. Sample Usage ------------ This sample is run using the tuscany binary distribution. To run it, navigate to this sample's directory and on Wondows, use following command: java -Dnotification.httpPort=8083 -cp ..\..\lib\tuscany-sca-manifest.jar;target\sample-binding-notification-producer.jar notification.producer.TrafficAdvisoryServer on *nix, use following command: java -Dnotification.httpPort=8083 -cp ../../lib/tuscany-sca-manifest.jar:target/sample-binding-notification-producer.jar notification.producer.TrafficAdvisoryServer this should bring up the following prompt: Send a report value, ^C or to end at this point you should be able to type a message to send, for instance: Traffic congestion Notice that before you try to send any message, you should bring up the consumer sample or the broker sample. When you have finished using this sample, type 'end' or ^C to end. Also notice that '-Dnotification.httpPort=8083' is used in the java command. This indicates the port the sample should use. This also says that this server is going to play the role of ntm, given our previous assumption. It is important that the first one of the producer, consumer or broker sample that is run be the one that uses '-Dnotification.httpPort=8083', otherwise there is no ntm to talk to and an exception will be thrown.
