Creating Web services using Apache CXF (Part 1) : The Basics.

As we discussed in the previous post, CXF is the combination of two projects: Celtix developed by IONA and XFire developed by Codehaus working together at the Apache Software Foundation.

If you want an Enterprise support  for CXF then please find the following links.

CXF Developer Advantages

• If you know Spring then CXF is too easy for you. All its configurations are in a Spring xml file. Internally CXF is reading this Spring XML as its Configuration file.JAX-WS encompasses many different areas:
  • Generating WSDL from Java classes and generating Java classes from WSDL
  • Provider API which allows you to create simple messaging receiving server endpoints
  • Dispatch API which allows you to send raw XML messages to server endpoints
• CXF implements the JAX-WS APIs which make building web services easy.
• Aegis Databinding (2.0.x) is a databinding library that makes development of code-first web services incredibly easy.
• CXF enables the development of RESTful services via annotations using the HTTP Binding.

It has a lot many features more to say. Once you got your project requirements and clear with the approach which you want to follow then please have a look on this feature list. I think you definitely will choose CXF without any doubt. [I am exerting some of the features from its own site]

General

• High Performance
• Extensible
• Intuitive & Easy to Use
