14   * This service is the gateway used to pass requests to the credit agency service.  For the sake of the example we've added
15   * some complexity here.
16   * 1) We use a _component binding_ to bind the {@link org.mule.example.loanbroker.credit.CreditAgencyService} to the remote
17   * CreditAgencyService EJB instance.
18   * 2) The argument passed into this interface binding is {@link org.mule.example.loanbroker.messages.Customer} but the EJB instance
19   * needs only a String (name) and Integer (ssn). Also the EJB service returns an XML message, but we convert it to a {@link org.mule.example.loanbroker.messages.CreditProfile}
20   * object. We demonstrate how to perform argument transalations by configuring transformers and response-transformers on an endpoint.
