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 is
that they are language and platform independent, that is to say, for example, a web
service developed in Java may 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
), 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 are covered in the next chapter.
