Part I. Starting from Java Code

Summary

One of the advantages of JAX-WS is that it does not require you to start with a WSDL document that defines their service. You can start with Java code that defines the features you want to expose as services. The code me be a class, or classes, from a legacy application that is being upgraded. It may also be a class that is currently being used as part of a non-distributed application and implements features that you want to use in a distributed manner. You annotate the Java code and generate a WSDL document from the annotated code. If you do not wish to work with WSDL at all, you can create the entire application without ever generating WSDL.
