Feature

The SOAP component is a Binding Component (BC) which enables to interact with external Web Services and to expose JBI services as Web Services.

In provider role, when a JBI MessageExchange is sent to a ServiceEndpoint (mapped to a Web Service), it is transformed into a SOAP message and sent to the linked external Web Service. In consumer role, when a SOAP message is received on an exposed Web Service, transformed into a JBI MessageExchange and sent to the corresponding JBI ServiceEndpoint.

The SOAP component is based on Apache Axis2 v1.5.1 (http://ws.apache.org/axis2/) and Mortbay Jetty v7.1.2 (http://jetty.codehaus.org/jetty/). It provides the following features :

• Expose JBI Services as SOAP Web Services
• Expose SOAP Web Services as JBI Services
• Handle SOAP attachments. The attachments of the incoming SOAP message are placed into the JBI message as attachments; the JBI attachments are placed in the outgoing SOAP message as attachments.

If you want more details about SOAP, you can consult this W3C specification : http://www.w3.org/TR/soap/. All attachment are processed by using XOP rules. (XML-binary Optimized Packaging : http://www.w3.org/TR/xop10/)
