Welcome to the Expresso Developer's Guide! This manual provides the Java developer with the information needed to take full advantage of the Expresso Web Application Development Framework and Component Library.
It gives you in a (fairly) concise form the net results of many thousands of hours of programmer time spent working with Expresso and developing best practices for it's use and implementation.
This guide is the result of many contributions, ideas, input and work by the Expresso developer's community, and we welcome any input, suggestions, and comments on it. Our goal is to continue to improve it as Expresso itself improves, so that it can continue to serve as a valuable tool for the professional developer.
The guide can be read in sequential order, as it starts by providing an overview of the tools and capabilities embodied by Expresso, then goes on to provide the details of those tools, and how to put them quickly to use in developing your own applications.
This guide is intended to supplement the the JavaDoc for Expresso. One of the best detailed references for Expresso is the JavaDoc, which you can download along with Expresso's source code. The source code itself, of course, is the ultimate authority on what's in Expresso, and should be referred to as required.
Furthermore, Expresso is based on Struts. So all of the Struts documentation applies, and should be considered a prerequisite. For example, features like "tiles" (a means for sophisticated #includes and template within JSP views) and "style" (a means for redirecting output to an arbitrary JSP) are useful but documented elsewhere in Struts and associated pages.
