WSIF Example
Web Services Invocation Framework (WSIF) provides a Java API for calling Web services, hiding the details of how the service is provided, i.e., via SOAP, JMS, etc. The following guide describes the ServiceMix components that integrate with the Apache Web Service Invocation Framework (WSIF)to perform web service invocations using a number of different implementation protocols such as Axis, local Java, EJB, JMS, JCA and CCI.

MDB | This MDB is the actual implementation of the service. It acts like a message listener on the queue specified in the config files. When a message is delivered, it extracts the body which is a ZIP Code. It then applies some logic to determine whether DSL service is available at this ZIP Code or not. For simplicity, it just returns true for all ZIP Codes < 50000 and false otherwise. The return message is sent to the queue specified in the replyTo field of the request message. NOTE: The MDB must encode the correct JMSCorrelationID in the return message in order for it to be picked up by WSIF. |

Following is an example of how to enable a service to be exposed over a JMS topic or queue. This is a snippet of code from the service.wsdl file. It shows how to configure the JMS binding:
