After you have developed the Java artifacts necessary to develop a Java API for XML-based RPC (JAX-RPC) web service, you must complete the Enterprise JavaBeans (EJB) implementation to assemble a Java archive (JAR) file or a web application archive (WAR) file based on your programming model. The resulting JAR file or WAR file contains the Enterprise JavaBeans (EJB) implementation and the supported classes created from the tooling.
Develop EJB implementation templates and bindings from a WSDL file for JAX-RPC web services using the wsdl2java command-line tool. The deployment descriptor templates that are generated from a Web Services Description Language (WSDL) file are required to complete the EJB implementation in the web services development process.
For JAX-RPC applications, complete the enterprise beans implementation by writing your business application.
Now that you have gathered the required artifacts for developing a JAX-RPC web service with an enterprise bean, you need to, configure the webservices.xml deployment descriptor.
