Writing a WS-Notification application that exposes a web service endpoint

Write a Java™ EE application, containing a web service definition, that can be deployed to the application server and act as a NotificationProducer, NotificationConsumer or demand-based publisher.

Before you begin

This task assumes that you have the following resources:
  • An installed and functioning copy of IBM® Rational® Application Developer, Rational Software Architect or equivalent tooling.
  • The WSDL file for the endpoint that is to be exposed.

About this task

To write a WS-Notification application that exposes a Web service endpoint, follow the method provided by your tooling for creating a web service implementation from a WSDL file. For example in Rational Software Architect there is a wizard in the Tutorials Gallery under Create and deploy a WS-I compliant web service and an enterprise bean skeleton from a WSDL document by using the WebSphere® Application Server runtime environment. This wizard guides you through the following steps for writing a JAX-RPC application.

Procedure

  1. Create a Dynamic Web Project.
  2. Import and validate the WSDL file.
  3. Create the web service.
    Select File > New > Other > Web services > Web service wizard > Skeleton EJB web service.
  4. Implement the business methods in the generated EJB class.
    The methods you choose depend upon the type of endpoint that you are exposing (NotificationProducer, NotificationConsumer or demand based publisher).
  5. Export the application.

What to do next

You are now ready to deploy the application to WebSphere Application Server with the console. In the Select installation options panel, ensure that the Deploy web services option is enabled.
