SOAP Web Services
with JAX-WS
Web Services allow us to develop functionality that can be accessed across a
network. What makes web services different from other similar technologies such
as EJBs or Remote Method Invocation ( RMI ) is that they are language and platform
independent, for example, a web service developed in Java might be accessed by
clients written in other languages and vice versa.
In this chapter, we will cover the following topics:
• Introduction to web services
• Creating a simple web service
• Creating a web service client
• Exposing EJBs as web services
Introduction to web services
Web services allow us to write functionality that can be accessed across a network in
a language- and platform-independent way.
There are two different approaches that are frequently used to develop web services:
the first approach is to use the Simple Object Access Protocol (SOAP) and the second
approach is to use the Representational State Transfer (REST) protocol. NetBeans
supports creating web services using either approach. SOAP web services are
covered in this chapter. RESTful web services were covered in the previous chapter.
