Problem

You want to convert an existing JSP-based web application to a Struts application.

Solution

Take a refactoring-style approach by applying Struts as you add new features to your application. As you increase your Struts knowledge, you can re-architect the existing code to use Struts. If no new development is planned for the application, refactor the existing JSPs a page at a time.

Discussion

The level of difficulty to migrate an existing JSP application depends greatly on the complexity and architectural soundness of the application. If the application uses a Model 1 architecture—that is, all logic is contained in the JSP page—it could be quite a challenge. You may find that you need to redesign the application from scratch to separate out the business logic from the presentation before you begin.

If you are new to Struts, then learn Struts on development of a new application instead of attempting to retrofit Struts to an application well into development. Struts is not a technology that can easily be "bolted on" late in the development process. However, some projects have altered their architectural underpinnings in midstream. If you are in this situation, steer the project plan so Struts is applied to new development first and preferably to features not on the critical path. Once you increase your Struts knowledge, it will be easier to convert existing code.

To make this more concrete, consider a simple example consisting of three JSP ...
