A shameless plug for my book "Spring Enterprise Recipes," from Apress. The book covers all manner of topics including business process management, batch processing, web services, messaging, schedulers, application integration, distributed computing and clustered caching. The book provides a discussion of all these techniques as well as prescriptions for Spring and various other libraries to build real-world, practical solutions. I hope you'll consider it for your next purchase.

Many applications are implemented with a three-tier architecture wherein data is stored in the database. The web server runs Java services that access the database and retrieve the information. The Java classes are responsible for the business logic that receives a call from the client tier, assembles the information from the database, and returns the result. The client tier utilizes browser technology that runs a Flash application to provide an interface to the user and calls the Java services for required information. The client workstations call the Tomcat server, which calls the database to gather data and executes the Spring services that contain the application’s business logic.

Rene Schulte extended his Silverlight 4 webcam and edge detection shader sample. He added a functionality to save webcam snapshots as JPEG files and discusses some limitations of Silverlight's built-in CaptureSource.AsyncCaptureImage snapshot method. Furthermore he gives some ideas on how to build a Silverlight 4 video chat / conference application on top of the JPEG capturing and encoding code.

A high quality HTML/CSS framework needs to have four attributes: useful, universal, usable, and unobtrusive. The four U’s. “Meiert’s four U’s” if you like, says a son of marketing gurus.

Not long ago i came across this cool Java framework for building your own web applications. Actually I think someone posted it at Twitter ( @playframework ). At first i saw the invitational presentation which you can find here or at the framework’s page.

This article specifies the steps to create the commonly used charts in a JSF application with the use of Primefaces.

This post explores three possible strategies that should help create good quality, uncoupled code: Simple Dependency Injection (DI), the Service Locator pattern and a DI framework. This includes a bespoke implementation of a DI framework.

Processing user-supplied form data can be fraught with errors. Not so with the Zend Framework! This tutorial shows you how to use the Zend Framework's Zend_Validate component to easily and conveniently validate complex form data.

Chris Coyier authored a post titled Better Pull Quotes: Don’t Repeat Markup a while back. In his post he created great-looking pull quotes without repeating any content — instead he uses jQuery to dynamically create the pull quotes. The following is the MooTools method for doing so.

In this great post by Jimmy Bogard or this Dimecasts on the subject we take a look at how to add IoC (Inversion of Control) support to your WCF application in order to support DI (Dependency Inversion). However, the one thing both the post and Dimecasts fail to take into account is what if you are not hosting your WCF service in IIS?

At the PDC (our dev conference) we release the Beta version of the ASP.NET Ajax Library and also donated it to the CodePlex Foundation as their first project. For this version of the library we’ve focused on four areas of functionality:

I made the fairly bold statement at my PDC09 talk that a DomainService IS A WCF Service. That is, everything you know about a WCF service should be true of a DomainService. I didn’t have time to get into this in my talk, so I thought I’d hit the highlights here. And in the process show how to consume a DomainService from a WinForms.

Following Kevin Pang’s request on my last post regarding my problems getting NHibernate, NH Spatial and SQL Server Fulltext queries to work, I am finally getting around to giving some tips and pointers, and the code that Steve Strong of iMeta knocked up for me.

Looking over the previous three posts, we have been working within a single assembly for managing our extensibility parts. While this works well if we want to use MEF more as an IoC container, it really limits the extensibility of our application. In the single assembly model that we've been using, every update would require a new build of the application. To overcome this limitation, we'll create a new example project that builds on what we've covered and branch it out into multiple assemblies.

I have attended a presentation by Simon Guest from Microsoft on their cloud computing architecture. Although there was no new concept or idea introduced, Simon has provided an excellent summary on the major patterns of doing cloud computing. I have to admit that I am not familiar with Azure and this is my first time hearing a Microsoft cloud computing presentation. I felt Microsoft has explained their Azure platform in a very comprehensible way. I am quite impressed. Simon talked about 5 patterns of Cloud computing. Let me summarize it (and mix-in a lot of my own thoughts) ...

Microsoft .Net Framework 4.0 and Visual Studio 2010 screenshots

Parameters are a key idea in Joomla development. It is almost an understatement to say that they are used to customise modules, components, plug-ins and templates. In many cases parameters provide the basic data that makes the addition function.

This article is used to configure JSF and Richfaces in Netbeans 6.x

Visual WebGui brings the Win(dows) Over Web revolution which uses well known Visual Basic .NET (VB .NET) development paradigm for web and cloud.

A few weeks ago I wrote a blog entry entitled Microsoft Semantic Engine where I spoke about a technology called (unsurprisingly) the “Microsoft Semantic Engine” which looks like it is set to ship in a future version of SQL Server.
