This example shows critical code snippets from a larger example, which can be found at: Apache Web Services Project. The original example has a A client application submitting submits a zip code to a Web Services application via a JMS queue. The web service checks if DSL service is available in the zip code area and responds to the client. In the original example, the client , also by sending a JMS message. The client software uses WSIF to hide the implementation details of JMS.
...
The example also shows an important feature of the ServiceMix Client API - how to bind a WSDL file for a web service, which is adorned with WSIF additional metadata to configure the service implementation. In other words, the service.wsdl file has The following snippet is from the servicemix.xml file. Note: that the WSIFBinding class has the service.wsdl file as a property.

MDB | This message driven bean 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 presumably a valid 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 that the bean must encode the correct JMSCorrelationID in the return message in order for it to be picked up by WSIF. |
