We like to replace a existing WebSerivce(Java) running on a GLUE to a WBI Message flow web service. What are the steps involved in developing a message flow as a web service. (I am new to WebServices on WBI).Your help is much appreciated.
Thanks. |

Why are you reimplementing existing webservice into message broker ? SOA Strategy always recommends to resuse the existing infraustucture rather than reimplementation.
Secondly, any message broker or any ESB tools (IBM or non-IBM) is not for application/service development. ESB tools are always for service integration. Message broker HTTP nodes (Input and Reply) are provided so that any MQ based applications can be exposed as webservice so that integration between webservice and non webservice based application is possible. From Architectural point of view, HTTP nodes (Input and Reply) are for protocal switching not for building webservice in middleware layer.

Thanks Sourav & EAI Develoepr
Let me explain my requirement and why i am planning to use WBI for integration.We get a request from backend(mid range) system in a BLOB format , that needs to be converted into XML and call a internal Web Service (hosted on a diff system). Response back will be a XML format and convert back to BLOB and route to a back-end system. (Response service can't drop a MSG into MQ Queue, so the message flow has to be a Web Service which can consume XML response).
Let me know if WBI is the best choice for my above requirement.
Thanks. |

rsashi,
What is the problem in using that internal web service to call from Message Broker and once you get te response from the web service, you can convert it back to BLOB with not much difficulty. For that you dont need to implement web service in WMB rather you will need HTTPRequest node call the web service.
