Web services with ServiceMix and CXF

This tutorial teaches you how you can use the CXF components for building a new web service in ServiceMix.

Goals of the document

This tutorial shows you how to create a new web service using the servicemix-cxf-se JBI component. You will also learn how to expose this web service to the outside world over HTTP/SOAP with the servicemix-cxf-bc. The web service we will create is a very simple greeter application: if a client sends a user name in the request, the service will respond with a friendly greeting message.

Apache CXF

The Apache CXF framework is an open source framework which helps you develop webservices using frontend programming APIs like JAX-WS.
These services can communicate over many protocols (e.g. SOAP, XML/HTTP, RESTful HTTP) and transports (e.g. HTTP, JMS or JBI). You can also use interceptors to easily add behavior to the services stack.

Goals

After this tutorial...

you can use Maven to develop JBI service units and service assemblies
you can use xbean.xml files to configure the ServiceMix CXF components
you know how to use a WSDL file to define your web service
you know how to implement web services using Java classes

Prerequisites

Before starting this tutorial, you should...

be able to use ServiceMix (start/stop the container, deploy service assemblies, ...) (→ tutorial 1)
know how to use the Maven archetypes and JBI plugin to build and deploy your projects (→ tutorial 2)
know how to develop Java classes and build them using Maven
have a basic knowledge about web services (e.g. WSDL, SOAP, ...)

1.01 Creating the Maven project — create a Maven project which will contain our SU and SA projects
1.02 Creating cxf-bc service unit — create the cxf-bc service unit.
1.03 Configuring the cxf-bc-su service unit — configure the cxf-bc-su to provide our webservice
