In a nutshell: </p> <ul> <li> <p>Most Java web frameworks require a server-side runtime component. With J2Page it is possible to build your interface solely on the client side, calling back to a web service or some other RPC mechanism to interact with the server as needed. In other words, developers can build pure Ajax solutions by writing their code in Java instead of JavaScript.</p> </li> <li> <p>Other frameworks that take a similar Java-to-JavaScript approach have proprietary APIs and class libraries. J2Page relies solely on the W3C standard DOM (Document Object Model). Rather than introduce its own proprietary API, J2Page is designed to take advantage of the numerous high-quality JavaScript Ajax libraries that are now appearing such as Dojo, OpenRico, YUI, etc.</p> </li> </ul> <p>For a more in-depth comparison on how J2Page fits in with other popular web development technologies, please see the following:</p> <ul> <li> <p> <a href="intro-jsf.html">Using J2Page with JSF</a> </p> </li> <li> <p>Comparison with Traditional MVC Frameworks (Using J2Page with Struts?)</p> </li> <li> <p> <a href="comparison-j2js.html">Comparison with Other Java-to-JavaScript Converters</a> </p> </li> <li> <p> <a href="comparison-js.html">Comparison with Pure JavaScript Ajax Solutions</a> </p> </li> </ul> </td> </tr> </table> </td> </tr> </table>  <script type="text/javascript"> var sc_project=2789452; var sc_invisible=0; var sc_partition=28; var sc_security="558f9528"; </script> <script type="text/javascript" src="http://www.statcounter.com/counter/counter_xhtml.js">  </script> <noscript> <div class="statcounter"> <a class="statcounter" href="http://www.statcounter.com/"> <img class="statcounter" src="http://c29.statcounter.com/2789452/0/558f9528/0/" alt="web metrics"/> </a> </div> </noscript>  </body> </html>
