+		<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 – 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>
+		
+		<h1>Find out more...</h1>
+		<table id="find_out_more">
+			<tr><th><a href="forms_controls.htm">Web form design and model / view
separation</a></th><td>See how Empire tags can make your form definition
both simpler and safer and learn how field access logic can be kept out 
+						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 –
Rendering and parsing</a></th><td>Understand the problem of form data processing
with traditional 
+				Web application frameworks and learn why it's sensible to 
+						keep rendering, parsing and validation of a value together in one easy to implement
class.</td></tr>
