Development-WO Adaptor

Version 25.1 by Ravi Mendis on 2011/05/03 21:26

Overview

The WOAdaptor layer of WebObjects can be thought of as a broker of requests and responses.  Its role in the framework is to:

  1. Receive incoming requests of some type (typically HTTP)
  2. Package them into a WORequest
  3. Dispatch the WORequest to the WOApplication
  4. Receive the WOResponse back from the WOApplication
  5. Send the response back across whatever protocol the adaptor handles

In most cases, you will be dealing with WODefaultAdaptor, which is provides support for HTTP.  However, adaptors could receive requests from any number of sources.  As an example, Project Wonder includes ERIMAdaptor, which provides support for requests and responses over Instant Messaging networks.

Netty WOAdaptor

The Wonder ERWOAdaptor framework includes a new WOAdaptor based on Netty.

AJP Adaptor

The LEWOStuff frameworks include a WOAdaptor which can be used to supply requests from an AJP supplier such as Apache2.
