That is when I found the javascript library <a href="http://extjs.com/">Ext </a>and the <a href="http://code.google.com/p/gwt-ext/">GWT-Ext</a> project which wraps the Ext javascript library so that you can easily use it in the GWT framework. This framework is AWESOME! It looks good, the framework is easy to learn and extend, and you get tons of functionality right out of the box.<br /><br />Now, I still think using Flex/Flash based clients with Grails or Rails(JRuby) servers are probably just as good since they follow the same concepts as my example application, but I'm not sure how easily Flex applications can be debugged. It probably works pretty well though given the Flex Builder IDE that Adobe has developed.<br /><br />Anyways, check out my sample GWT-Ext+Grails application <a href="http://www.brentryan.com/client">here (http://www.brentryan.com/client)</a> <-- Doesn't work sometimes because my IP address changes and too lazy to setup dynamic DNS. This application has complete separation between the client and server because the client makes RESTful like Http request to the grails back end and the grails server app returns JSON responses when needed. In this example I'm also generating charts using <a href="http://www.jfree.org/jfreechart/">JFreeChart </a>from the grails backend and displaying them in the GWT client.<br /><br /><span style="font-weight: bold;">Example application login/password</span><br />username: admin<br />password: admin<br /><br />Email if you have any questions brent.ryan@gmail.com<br /><br />Source code for this example can be found <a href="https://code.google.com/p/example-gwt-grails/">here</a><br /><br />Pre-built client and server war files can be downloaded:<br />Download --> <a href="http://www.brentryan.com/client.war">client</a><br />Download --> <a href="http://www.brentryan.com/server.war">server</a><br /><br />Update: GWT-Ext 2.0 was released and requires much of these api's to be updated. Check out the live <a href="http://www.gwt-ext.com/demo">demo</a>. I think it's very impressive.<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/2465719483363596047-776286734767645552?l=geekyryan.blogspot.com' alt='' /></div>Brent Ryanhttp://www.blogger.com/profile/11029327635235643876noreply@blogger.com17
