Developers decorate Java programming language class files with HTTP. The JAX-RS API uses Java programming language annotations to simplify the development of RESTful web services. To build the client, you must first have deployed HelloServiceApp, as described in " Packaging and Deploying the Service with asant. The JAX-RS API for developing RESTful web services is a Java programming language API designed to make it easy to develop applications that use the REST architecture. Maven runs the openapi plugin during the integration-test phase. The springdoc-openapi-maven-plugin plugin works with the spring-boot-maven plugin. Public class HelloClient HelloService service The springdoc-openapi library provides a Maven plugin, springdoc-openapi-maven-plugin, which generates OpenAPI descriptions in JSON and YAML formats. These are the basic steps for creating the web service and client: Together, the wsgen tool and the Application Server provide the Application Server's implementation of JAX-WS. You can still use webservices.xml to augment or override existing JAX-WS annotations. For JAX-WS Web services, the use of webservices.xml is optional. For reference documentation on wsgen, see the Application Server man pages at. at runtime to control how the JAX-WS runtime processes and responds to Web service invocations. You use the endpoint implementation class and the wsgen tool to generate the web service artifacts and the stubs that connect a web service client to the JAX-WS runtime. You must then provide a SEI that defines the public methods made available in the endpoint implementation class. Java API for XML Web Services (JAX-WS) is a standardized API for creating and consuming SOAP (Simple Object Access Protocol) web services. You may specify an explicit SEI by adding the endpointInterface element to the WebService annotation in the implementation class. The web service implementation class implicitly defines a SEI. An SEI is not required when building a JAX-WS endpoint. The WebService annotation defines the class as a web service endpoint.Ī service endpoint interface (SEI) is a Java interface that declares the methods that a client can invoke on the service. The starting point for developing a JAX-WS web service is a Java class annotated with the annotation. Figure 1-1 Communication Between a JAX-WS Web Service and a Client
