With development artifacts you can develop an enterprise bean or a Java bean module into a Web service. This topic describes artifacts used to develop Web services that are based on the Web Services for Java 2 Platform, Enterprise Edition (J2EE) 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 runtime that you are using.
For JAX-RPC applications, the webservices.xml file contains the J2EE deployment descriptor of the Web service specifying how the Web service is implemented. The webservices.xml file is defined in the Web Services for J2EE specification. For JAX-WS applications, deployment descriptors are not supported and have been replaced by the use of annotations.
This file contains WebSphere product-specific deployment information and is defined in ibm-webservices-bnd.xmi assembly properties.
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 For JAX-WS applications, deployment descriptors are not supported and have been replaced by the use of annotations.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.
