RCP & RAP. Single source code

In this article, we will try to describe how we can maintain an Eclipse Rich Client and Web Rich Client with same source code. The RAP (Eclipse Rich Ajax Platform) project enables developers to build rich, Ajax-enabled Web applications by using the Eclipse development model, plug-ins with the well known Eclipse workbench extension points and a widget toolkit with SWT (Swing Widget Toolkit) API (plus JFace). RAP is very similar to Eclipse RCP (Rich Client Platform), but instead of being executed on a desktop computer RAP is run on a server and clients can access the application with standard browsers. This is mainly achieved by providing a special implementation of SWT (a subset of SWT API).
