JOKe's Blog: RichFaces server-side paging with DataTable.
"Most of the component toolkits have build in support for server-side paging this days but in rest of the cases you need to customize a little the data model or data provider or component itself to have data paging. The reason why I write this post is because when I first saw richfaces everythink was perfect except the server-side paging. They have paging but it was client side based on JavaScript witch just doesn't work in many cases and I loose a lot of time to understand all models, which model I must extend and how to do it to create a data model with server side paging. At the current version of RichFaces on the demo page information about how to do server-side paging at least exist http://livedemo.exadel.com/richfaces-demo/richfaces/dataTable.jsf?tab=dataModel&cid=3608154 but like always the JBoss/RedHat/Exadel doesn’t provide us a fast full easy working example and we must loose a lot of time to search for classes in the demo."

heise Developer - 09.10.2009 13:58 - Convention over Code in Java EE
-
Auch wenn es sich die Java-Community lange nicht eingestehen wollte, wurde spätestens mit J2EE 1.4 klar, das essenzielle Bereiche der Enterprise-Java-Plattform eine Sackgasse darstellten. Statt vereinfachter Anwendungsentwicklung und damit Fokussierung auf die Geschäftsprozesse standen Infrastrukturprogrammierung und Verstöße gegen das DRY-Prinzip im Vordergrund. Glücklicherweise gelang mit Java EE 5 ein erster wichtiger Befreiungsschlag mit richtungweisenden Konsequenzen. Java EE 6 behauptet nun, den seinerzeit eingeschlagenen Weg konsequent weiterzuverfolgen. Wohin er führt, zeigt heise Developer in diesem Artikel.
