The JSP pages of the <code class="cCode">bookstore5</code> application use the JSTL XML tags (see <a href="JSTL5.html#wp63716">XML Tags</a>) to manipulate the book data from an XML stream. The <code class="cCode">books</code> application contains the JSP document, <code class="cCode">books.jspx</code>, which accesses the book data from the database and converts it into the XML stream. The <code class="cCode">bookstore5</code> application accesses this XML stream to get the book data.</p><a name="wp118546"> </a><p class="pBody">These applications show how easy it is to generate XML data and stream it between Web applications. The <code class="cCode">books</code> application could be considered the application hosted by the book warehouse's server. The <code class="cCode">bookstore5</code> application could be considered the application hosted by the book retailer's server. In this way, the customer of the bookstore Web site sees the list of books currently available, according to the warehouse's database.</p><a name="wp116762"> </a><p class="pBody">The source for the Duke's Bookstore application is located in the <code class="cCode"><</code><code class="cVariable">INSTALL</code><code class="cCode">>/j2eetutorial14/examples/web/bookstore5/</code> directory created when you unzip the tutorial bundle (see <a href="About.html#wp63740">About the Examples</a>).
