Notification Consumer Binding Sample =============================== This sample illustrates the use of with a remote consumer. 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 consumer that is located in a separate (and remote) composite with respect to any producers. As such, this sample is run in conjunction with the binding-notification-producer 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 service, wired to 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. Building And Running The Sample Using Maven ------------------------------------------- With either the binary or source distributions the sample can be built and run using Maven as follows. cd binding-notification-consumer mvn Sample Usage ------------ This sample is run using the tuscany binary distribution. To run it, first set the following environment variables: set MAVEN_REPO= set NOTIFICATION_IMPL_JAR=%MAVEN_REPO%\org\apache\tuscany\sca\tuscany-implementation-notification\1.0-incubating-SNAPSHOT\tuscany-implementation-notification-1.0-incubating-SNAPSHOT.jar set NOTIFICATION_BINDING_JAR=%MAVEN_REPO%\org\apache\tuscany\sca\tuscany-binding-notification\1.0-incubating-SNAPSHOT\tuscany-binding-notification-1.0-incubating-SNAPSHOT.jar set STAX_JAR=%MAVEN_REPO%\stax\stax\1.1.1-dev\stax-1.1.1-dev.jar set TUSCANY_BIN_DISTRO= set TUSCANY_SCA_MANIFEST_JAR=%TUSCANY_BIN_DISTRO%\lib\tuscany-sca-manifest.jar Then navigate to this sample directory and do: java -Dnotification.httpPort=8082 -cp "target\sample-binding-notification-consumer-1.0-incubating-SNAPSHOT.jar;%NOTIFICATION_IMPL_JAR%;%NOTIFICATION_BINDING_JAR%;%STAX_JAR%;%TUSCANY_SCA_MANIFEST_JAR%" notification.consumer.TrafficAdvisoryServer this should bring up the following prompt: TrafficAdvisoryServer, hit return to end at this point you should be able to receive messages. Notice that before you try to receive any message, you should bring up the producer sample or the broker sample. When you have finished using this sample, hit return to end. Also notice that '-Dnotification.httpPort=8082' is used in the java command. This indicates the port the sample should use. This also says that this server is not 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.
