Interacting with Databases through the Java Persistence API

by Suhreed Sarkar | November 2008 | Joomla! MySQL Content Management Open Source PHP

The Java Persistence API (JPA) is an object relational mapping API. Object relational mapping tools help us automate mapping Java objects to relational database tables. Earlier versions of J2EE used Entity Beans as the standard approach for object relational mapping. Entity Beans attempted to keep the data in memory always synchronized with database data, a good idea in theory, however, in practice this feature resulted in poorly performing applications.

Several object relational mapping APIs were developed to overcome the limitations of Entity Beans, such as Hibernate, iBatis, Cayenne, and Toplink among others.

With Java EE 5, Entity Beans were deprecated in favor of JPA. JPA took ideas from several object relational mapping tools and incorporated them into the standard. As we will see in this article by David Heffelfinger, NetBeans has several features that make development with JPA a breeze.

ASP.NET MVC Framework

by Vivek Thakur | November 2008 | .NET Architecture & Analysis Microsoft

These days, Model View Controller (MVC) is a buzzword in the ASP.NET community, thanks to the upcoming ASP.NET MVC Framework that Microsoft is expected to launch soon. The Framework allows easier adoption of the different MVC patterns in our web applications.In this article by Vivek Thakur, we discuss ASP.NET MVC Framework in detail with the help of a Sample Project. We also take a glance at Unit Testing with reference to ASP.NET MVC Framework.

The ASP.NET MVC framework was released by Microsoft as an alternative approach to webforms when creating ASP.NET based web applications. The ASP.NET MVC framework is not a replacement or upgrade of webforms, but merely another way of programming your web applications so that we can get the benefits of an MVC design with much less effort.

Obtaining Alfresco Web Content Management (WCM)

by Jeff Potts | November 2008 | Content Management Open Source

People have been using Alfresco to manage web content since the early days of the product. In 2007, Alfresco released its formal web content management functionality that added features most people expect when they think of a Web Content Management (WCM) offering, including templating, site preview, snapshots, virtualization, and deployment. WCM is a specialized subset of the larger Enterprise Content Management (ECM) umbrella that is focused specifically on authoring, managing, and publishing files used to produce a website.

In this article by Jeff Potts, we will discuss how to create a web project and define web forms using XML Schema to allow non-technical users to create content.

Migration from Apache to Lighttpd

by Andre Bogus | November 2008 | Linux Servers Open Source

In this article by Andre Bogus, we will be focusing on migrating from Apache to Lighttpd web server. Lighttpd is the perfect solution for every server that is suffering load problems, as it has a small memory footprint compared to other web-servers, effective management of the cpu-load, and advanced feature set, such as FastCGI, SCGI, Auth, Output-Compression, URL-Rewriting, and many more. Apache is still the most common web server used today, so while we wait for Lighttpd's world domination, the migration from this server warrants its own article. As this article is on Lighttpd and not on Apache, it assumes some knowledge of the Apache configuration. If anything is unclear, the Apache documentation at will be of help.
