  1. Using a web-based form, a user asks for data from a legacy application.
  2. An HTTP request is formulated and sent to the HTTP binding component (BC). 2
  3. The HTTP binding component transforms the HTTP message in a neutral form. This is a normalized message.
  4. The normalized message is routed through the Normalized Message Router (NMR) to a Service Engine or BC that knows how to communicate to the legacy application.
  5. The SE/BC transforms the message into a form that the legacy application understands.
  6. The SE/BC passes the message to the resource adapter 3 for the legacy application.
  7. The resource adapter communicates with the legacy application and obtains the requested data.
  8. The data is transferred back to the web-based form, reversing the route. legacy/external app <-- resource adapter <-- |binding component (inside ESB) --> NMR -->
    binding component |--> resource adapter --> legacy app.

The following diagram illustrates this:

In comparison, the Basic example, looks like the following diagram. This is a simplified diagram of the basic example. For a complete diagram, please see: xxxx.
