The configuration elements

...

  1. Download the Messsage-Translator.zip file, which includes the ESB configuration described above. 
  2. See Setting up the Environment for instructions on setting up the ESB and the back-end service.

    Info

    When you set up the environment, note that you only need to start one instance of the back-end service (Stock Quote Service) to simulate this example.

Executing the sample

Send the following request to the ESB, by using a SOAP client. When you send the request, you will need the wsdl URL of the proxy service defined in the ESB configuration. The default wsdl URL for this proxy service is http://localhost:8280/services/message-translator-proxy?wsdl.
