WebSphere Application Server Version 6.0 complies with the Java 2 platform, Enterprise Edition (J2EE) EJB 2.1 specification by enabling you to expose an EJB stateless session bean as Web service.
You can do this by simply declaring a link between the desired Endpoint name in the Web service deployment descriptor of the EJB module. During deployment and installation of the bean into the Application Server environment, the bean is linked to the specified Web service endpoint.
If you are writing a stateless session bean to implement a preexisting Web Services Description Language (WSDL) interface, remember to implement in your bean all of the methods defined on the WSDL interface.
