Travel planning application

This demo is the skeleton of a more complex application. It demonstrates an architecture for supporting HTML and WML simultaneously while enhancing modifiability and testability. It also shows how to do session management for mobile clients. The architecture is described more fully in the presentation. The key points are:

• A ControllerServlet handles a request by delegating an Action class.
• The Action is specified by an init-param.
• Actions are beans whose properties correspond to HttpServletRequest parameters - the servlet initializes the properties
• Actions return an ActionResult that specifies the JSP page to display and contains the data (in the form of beans) to pass to the JSP page.

The application consists of the classes shown in the following diagram. Click on the class to see its source code.

Other classes include:

• DisplayBestFaresAction.java
