With development artifacts, you can develop an enterprise bean or a JavaBeans module into Web services that are based on the Web Services for Java Platform, Enterprise Edition (Java EE) specification.
The WSDL XML file describes the Web service that is implemented.
A Service Endpoint Interface is the Java interface corresponding to the Web service port type implemented. The Service Endpoint Interface is defined by the Java API for XML Web Services (JAX-WS) or Java API for XML-based RPC (JAX-RPC) Web services run time that you are using.
The webservices.xml file contains the Java EE deployment descriptor of the Web service specifying how the Web service is implemented. The webservices.xml file is defined in the Web Services for Java EE specification.
For JAX-WS Web services, the use of the webservices.xml deployment descriptor is optional because you can use annotations to specify all of the information that is contained within the deployment descriptor file. You can use the deployment descriptor file to augment or override existing JAX-WS annotations. Any information that you define in the webservices.xml deployment descriptor overrides any corresponding information that is specified by annotations.
For JAX-RPC applications, deployment descriptors are required to specify how the Web service is implemented.
This file contains WebSphere® product-specific deployment information and is defined in the ibm-webservices-bnd.xmi deployment descriptor. assembly properties. See the JAX-RPC Web services deployment descriptor settings information to learn more about this deployment descriptor.
The JAX-RPC mapping deployment descriptor specifies how Java elements are mapped to and from WSDL file elements.
The WSDL file is provided by the Web service implementer.
The Java interfaces are generated from the WSDL file as specified by the JAX-WS or JAX-RPC specification. These bindings are the Service Endpoint Interface based on the WSDL port type, or the service interface, which is based on the WSDL service.
This file contains WebSphere product-specific deployment information, such as security information for JAX-RPC applications. For JAX-WS applications, deployment descriptors are not supported and have been replaced by the use of annotations.
Additional JAX-RPC binding files that support the client application in mapping SOAP to the Java language are generated from WSDL by the WSDL2Java command tool.
