Real-time data validation is one of the advantages of AJAX technology. By applying this technology, the struts validation framework will enrich the struts MVC and move the Web application closer to the desktop application. The validation framework is used to validate fields. There are many ways to do validation on a Web application. It falls into two categories: server-side and client-side. A struts validation framework is one of the best frameworks for a Java-based Web application environment. It can configure the application using server-side validation and employ the error message that renders on the validation process invoked during the request processing time, or it can do client-side validation by using the JavaScript rendered on the requested page. AJAX is a JavaScript technology that can asynchronously call the server and fetch the XML documents that are so ... (more)

With a little experimental i have conduct, i would like to give you some of information that you might interesting on exploring this technology. Call Control / SI... (more)

A New Weapon in Developing Rich Client Applications

JavaFX is a scripting language that provides more powerful client applications in term of features for the user interface experience as well as being incorporated with server platform technology such as RMI, Web Services, and EJB. Its ability to reuse all Java libraries opens an opportunity for JavaFX to create flexibility and ease the integration and reuse of existing Java applications.  EJB (Enterprise Java Bean) is one of the technologies in the Java EE platform that currently most of the business application geared for deriving the logical business process.

.NET Application Logging Mechanism

In application development, one should consider an effective way of creating a standard rule for coding and debugging. For all the information provided in the application code, there's a better way for developers to track down a problem and find a solution. The logging mechanism is one of the low-tech solutions for serving up information for tracking down application code. In this article I'll try to provide a tutorial for using the Log4Net logging framework adapted from the log4j framework that's currently the most popular logging mechanism for the Java platform. Log4Net API T... (more)

Develop Web Services Clients

Interoperability is the key to using Web services architecture since many applications can collaborate to maximize business functions. With the capability of creating an application on a different architecture, including the application architecture, hardware infrastructure, and even the operating system, Web service architecture is the bridge to optimizing the IT Department. In this article we will create a simple Web service using an EJB application and we will create a Flash MX project as a Web service client interface. We will use Websphere SDK v5.0.1 for the server-side sce... (more)
