When you launch the wizard from the context menu on the Java class file in the Application Navigator, JDeveloper automatically populates the
Component To Publish field with the fully qualified class name.
If you launch the Create Java Web Service wizard from the New Gallery in the project, Java classes that are in the current project are listed in the
Component To Publish dropdown list, and you will be able to select the class to publish as a web service, or you can click
e to look for the class you want.
In either case, use the Generation Options page of the wizard to provide a name for the web service container and a name for the port.
