Creating a Web Service class
In this section, we take a look at the Java Web Service (JWS) file, which is simply a
Java class annotated with the @WebService annotation (
javase/6/docs/api/javax/jws/WebService.html ), for implementing a JAX-WS
Web Service. JSR 181: Web Services Metadata for the Java Platform defines the standard
annotations that can be used in a Java Web Service. The javax.jws.WebService
annotation specifies that a class implements a web service. All the attributes of the @
WebService annotation are optional. First, create a Java class by selecting Java Class
in the New Gallery . In the Create Java Class window, specify the class name as
EJB3WSImpl . A Web Service class gets added to the EJB 3.0 project. The Entity class
may also be made a web service by annotating it with the @WebService annotation.
However, creating a separate Web Service class provides the advantage of
de-coupling the Entity bean from the web service; if modifications are required
to the web service, the entity does not have to be modified.
