How to create a web service with JAX-WS?
You use the endpoint implementation class and the wsgen tool to generate the web service artifacts that connect a web service client to the JAX-WS runtime. Together, the wsgen tool and the Application Server provide the Application Server’s implementation of JAX-WS.
Do you need an interface to use JAX-WS?
a Java interface or class, respectively, that declares the methods that a client can invoke on the service. An interface is not required when building a JAX-WS endpoint. The web service implementation class implicitly defines an SEI.
What does JAX WS stand for in Java?
This leads to easy maintenance and easy to extend. Multiple service versions can be running at same time. JAX-WS stands for Java API for XML Web Services. JAX-WS is XML based Java API to build web services server and client application. It’s part of standard Java API, so we don’t need to include anything else which working with it.
Where to find the source code for JAX-WS?
The source code for the service is in the tut-install/examples/jaxws/helloservice-war/directory, and the clients are in the tut-install/examples/jaxws/hello-appclient/and tut-install/examples/jaxws/hello-webclient/directories. Figure 31-1illustrates how JAX-WS technology manages communication between a web service and a client.
How is the wsimport tool used in JAX-WS?
The wsimport tool is used to parse an existing Web Services Description Language (WSDL) file and generate required files (JAX-WS portable artifacts) for web service client to access the published web services.
Do you need an interface in JAX-WS?
An interface is not required when building a JAX-WS endpoint. The web service implementation class implicitly defines an SEI. You may specify an explicit interface by adding the endpointInterface element to the @WebService annotation in the implementation class.
How is a stub created in JAX-WS?
It makes this call through a stub, a local object that acts as a proxy for the remote service. The stub is created at development time by the wsimport tool, which generates JAX-WS portable artifacts based on a WSDL file. Coding the Client
