We will use the samples to illustrate how to bind web services with the ServiceMix ESB to facilitate integration.

We will cover the following in this chapter:

  • Web services and binding

  • Introduction to HTTP

  • ServiceMix's servicemix-http component

  • The consumer and provider roles for the ServiceMix JBI components

  • servicemix-http in the consumer and provider roles

  • Web service binding (Gateway) sample

Web services separate out the service contract from the service interface. This feature is one of the many characteristic required for an SOA-based architecture. Thus, even though it is not mandatory that we use the web service to implement an SOA-based architecture, yet it is clearly a great enabler for SOA.

Web services are hardware, platform...
