Write a WS-Notification application that does not expose a web service endpoint
Write a Java EE application that can be run outside of the application server to make web service invocations against an external web service. This application acts as a lightweight publisher, or a pull type consumer by invoking web service operations against another web service such as the NotificationBroker provided by WAS. This task assumes that we have the following resources:
To write a WS-Notification application that does not expose a web service endpoint, follow the method provided by your tooling for creating a web service implementation from a WSDL file. As an illustration, the following steps describe the method provided by Rational Software Architect for writing a JAX-RPC application. The steps are very similar for writing a JAX-WS application. For examples of JAX-WS publisher and subscriber client applications that do not expose a web service endpoint, see Writing JAX-WS applications for WS-Notification.
- An installed and functioning copy of IBM Rational Application Developer, Rational Software Architect or equivalent tooling.
- Knowledge of where to find the WSDL file for the service that is to be invoked.
Procedure
- Get the WSDL files for the service to invoke. If the target service is the notification broker service that was generated by WAS, use the administrative console to publish the WSDL files for the service to a compressed file.
- Create a Dynamic Web Project with a name of your choice.
- Choose File > New > Other > Web services > Web services Client.
- Select Java Proxy.
- Enter or select the WSDL you obtained earlier.
- Choose a Client Type of "Application Client" or " Java " depending upon your requirements.
- Select your required security configuration.
- Click Finish.
- Use the generated proxy and stubs to make calls against the remote web service. For detailed coding examples, see Develop applications that use WS-Notification.
What to do next
You are now ready to deploy the application for use in the Java EE application client container as described in Run a Java EE client application with launchClient.
