+
+ <h1>Empire-Struts2-Extensions</h1>
+ <p> Empire-db has not been designed for any specific type of application or
+ front end framework and
+ is thus suitable likewise for Rich-client, Web or command line applications. However
+ unlike with other data persistence solutions, Empire-db's metadata support can be
+ utilized and extended to work all the way through to the presentation layer and
+ dramatically reduce redundancies which are otherwise necessary to shape the user
+ interface. This in turn significantly reduces the errors caused by inconsistencies
+ between view and model â and opens even more opportunities for a cleaner separation
+ of model and view. This together with the compile-time safety provided by object
+ references can improve code quality and reduce both coding and testing effort.</p>
+ <p> In order to take full advantage of these features however some glue
+ code may be required and convenient to help the presentation layer understand the model. For a Web application
+ framework for example all of Empire-db's metadata can be used directly to supply every
+ single attribute value of an HTML tag, but it is a lot more convenient to use special
+ tags that directly understand Empire-db's data and metadata interfaces and get the
+ information they need themselves.</p>
+ <p> As the first Web application framework we have chosen to provide special support for
+ the popular <a href="http://struts.apache.org/2.x">Apache Struts2 framework</a>.
+ While Struts2 is a well appreciated and capable framework by itself, we think that in
+ combination with Empire-db and our extensions library serving as the glue between the two,
+ it really rocks. We believe that data based Web application development has never been
+ safer and more efficient.</p>
+ <p> The following graphic shows the basic difference:</p>
+ <table id="struts2_comparison">
+ <thead>
+ <tr><th>Struts 2 with traditional integration</th><th>Struts2 with Empire-Struts2-Extensions</th></tr>
+ </thead>
+ <tbody>
+ <tr><td><img src="../images/diagrams/struts2-traditional.gif" alt="Struts 2 with traditional integration" /></td><td><img src="../images/diagrams/struts2-empire.gif" alt="Struts2 with Empire-Struts2-Extentions" /></td></tr>
+ </tbody>
+ </table>
+ <p> At its heart, Empire-Struts2-Extensions offers a set of special tags which are specifically designed to work with Empire-db's data and
+ metadata objects and which can be used instead or in combination with standard Struts2 tags.</p>
+ <p> This however is just part of the story. In addition its unique input control mechanism combines
+ the tasks for rendering, parsing and validating data in one single class. Its pull rather than
+ push request parameter handling makes a huge difference whenever special display formatting and
+ input control combinations are required.</p>

+ of the JSPs offering a much cleaner separation of model and view at no cost.</td></tr>
+ <tr><th><a href="rendering_parsing.htm">Input controls part 2 â Rendering and parsing</a></th><td>Understand the problem of form data processing with traditional
