Introduction

In this article, you will use CXF and Spring to build and develop an order Processing Web service. The WEB service processes or validates orders placed by the customer and returns a unique order ID. After reading this article, you will be able to apply the concepts and features of CXF to build and develop WEB services.

System Requirements

To run the examples in this article, make sure that the following software has been installed and set up on your computer:

Java 5 or later

Tomcat 5 or later

ANT Build Tools

CXF Binary Distribution version 2.1

After you install the above distribution, set the following environment variables:

Java_home (for Java)

Catalina_home (for Tomcat)

Ant_home (for Ant)

Cxf_home (for CXF)

For example, you can set up cxf_home=c:\apache-cxf-2.1 and add the following content to the PATH environment variable:

Java_home\bin
