The source code for the HTTP Binding example is located in the ServiceMix installation directory under the examples\http-binding
directory in the servicemix.xml
file. It is recommended that you refer to the source code while reading this document.
This example invokes a web service to ask for a stock price. This example shows how to use an HTTP binding to handle a simple HTTP post. One component acts as the HTTP server, which listens on http://localhost:8912, while another component invokes a remote service, implemented as an URLEndpoint. A simple HTTP client is provided so that a simple post can be sent to the server.

jbi | jbi is the "id" of the JBI container and provides the basic infrastructure services for the following components: httpReceiver and stockQuote. During initialization, several singletons are instantiated: URLEndpoint and JBI. After initialization, the components in the JBI container are activated. |
httpReceiver | This component is an HTTP server that listens at http://localhost/8912![]() . It forwards the message it receives from this URL to stockQuote as specified in its destinationService property in the |
stockQuote | This is a SaajBinding component that invokes an endpoint service called soapEndpoint. It is implemented by the SaajBinding class which converts an inbound JBI message into a SAAJ (Soap With Attachments for Java) request-response and sends the response back to httpReceiver. This provides a message centric way of invoking SOAP services inside providers such as Apache Axis. This component invokes a web service to get a stock price. |
soapEndpoint | A URLEndpoint object contains a URL, which is used to make connections to the remote party. A stand-alone client can pass a URLEndpoint object to the SOAPConnection method call to send a message. |
