You can use the Java™ API for XML-based RPC (JAX-RPC) programming model to develop Web services.
To develop Web services based on the JAX-RPC programming model, you can use a bottom-up development approach starting from existing JavaBeans™ or enterprise beans or you can use a top-down development approach starting with an existing Web Services Description Language (WSDL) file. This task describes the steps when using the bottom-up development approach.
When developing a JAX-RPC Web service starting from existing JavaBeans or enterprise beans, you need develop a WSDL file. You can use existing JavaBeans or enterprise beans and then enable the implementation for Web services. Enabling the bean for Web services includes developing the service endpoint interface, developing a WSDL file that is the description of the Web service, generating and configuring the deployment descriptors, assembling all artifacts required for the Web service, and deploying the application onto the application server.
JavaBeans exposed as JAX-RPC Web services are supported only over an HTTP transport.
You have developed a JAX-RPC Web service application.
After you deploy the EAR file, test the Web service to make sure that the service works with the application server.
