Google Web Toolkit (GWT) and Java Servlets used in one web application. This tutorial will take you though the steps of developing a simple web application with Google Web Toolkit and J2EE Servlet Technology.

We're all familiar with the "OK" and "Cancel" buttons you get on dialog boxes. Simple labels that ask us whether we agree or disagree to the next action the application wants to take. The interesting thing is that using exclamations like "OK" and "No" isn't all that usable. Instead, you should use verbs. Let me illustrate this with an example.

Most sites that need to do full-text search of their content start with a simple "select * from blog where content ilike '%queryString%';". That often works in the test environment where there are only a few rows, but it breaks down quickly with a large corpus and more demanding searches. Lucky for us, the Apache Lucene project has a great framework for doing full-text searches, and the Hibernate team has integrated it with the Hibernate ORM, and the Seam and JBoss teams have made it available as a Seam-managed EntityManager. But don't worry, it's easy to use; we'll show how in a real-world Seam project.

Developing rich desktop Java applications has been historically a painful experience; but now you have new advanced Swing components and a complete application framework in the NetBeans Platform. See how the NetBeans Platform has made it much easier to develop a complex desktop application and the lessons learned in building it.

Murphy’s Law tells us that whatever can go wrong will go wrong. This axiom applies to all aspects of life, including data warehousing. The following corollaries to Murphy’s Law relate this inevitability of something going “bump” in the night to data warehousing.

In this tutorial, we will first add a count for the number of flags grabbed by the player. Then we will remove the timed random positioning of the flag and instead, we will add checks to see if the player's vehicle has “grabbed” the flag.

Many winners employ dashboards to give users a single overview of complex information and use lightboxes to ensure that users notice dialogs. Also, the Office 2007 ribbon showed surprisingly strong early adoption.

Nice overview of the new JSR 296 Swing Application Framework

Code Samples is a collection of code snippets exemplifying the Java programming language and other languages. Example code comes from various published documents on java.sun.com, and are also provided by the developer community. Use Code Samples for your own programming, and add your own examples to this collection.

Comprehensive article for web developers looking to educate their prospective (or current) clients on why they should use a Web CMS; also for individuals, companies, or web developers curious about investing in a WCMS-ready website. Includes a financial twist, appropriate for the dwindling economy.

Futuristic GUI design is sought after by companies in niches like electronics, software, and gaming. It's a style of design that requires intensive Photoshop skills. Let's take a look at some artists that are masters in this area of design. We'll point you in the direction of some beginner tutorials on the subject. Also, let's look at some additional resources where you can continue to be inspired and hone your skills.

Are you one of those people who need something more to get you excited about the future of virtual worlds than, “I am in ur browser, chatting in 3D?” Well, perhaps, it is time for you to take a close look at the burgeoning open source ecosystem surrounding OpenSIm.

My number one wish for Java desktop for this year was cross-platform support for H.264 and FLV formats. Today has marked a first (and hopefully not last) step towards playing video content in Swing application - Java Media Components which is a part of JavaFX preview SDK.

A new CSS engine for Java which makes it simple to apply styles to your Swing (and eventually JavaFX) programs. With advanced features like programmatic selectors and animated transitions between states, you owe it to yourself to check this out if you create GUI applications.

Is your mind like every one else in computer science?? or are you able to solve this small logic puzzle?? most people in computer science gets this one wrong! You have been warned!

Scene Monitor allows a user to visibly explore the structure of a scene graph while the application is running. A tree model captures all elements of the jME scene graph and allows for easy visual inspection.

This howto mainly contains information about, and links to, various AI related software libraries, applications, etc. that work on the GNU/Linux platform. All of it is (at least) free for personal use.

Over the course of the past few weeks the command button component in Flamingo component suite has been enhanced following the feedback from the project users. There is nothing better than getting the feedback from real-world use, and it is much appreciated on my side. Many thanks go to Kenneth Flynn and Christian Hebert for finding time to report these issues.

The first pattern I want to talk about is the Strategy pattern, which always reminds me about the Command & Conquer games so I’ll simply use it as an example :) First of all, the definition: “Define a family of algorithms, encapsulate each one, and make them interchangeable. Strategy lets the algorithm vary independently from clients that use it.

What happens when we run main()in the code snippet below? Of course, the erudite, tech-savvy Java people can answer that in a heartbeat. In Effective Java, 2nd ed., Joshua Bloch says in his machine such a program never stops running. Not that I have a self-esteem problem or whatever, but when it comes to Java, if I have to choose whether to trust Joshua Bloch or me, I choose the former. Sorry, me.

This is a story about creating a user interface easily, or better yet, about having good user interfaces without working for them.

There are many, many different kinds of portals. The Merriam-Webster's Online Dictionary contains five definitions for portal as a noun, ranging from a door to the entrance of a bridge and ending at "a site serving as a guide or point of entry to the World Wide Web." This article (and the portal it is published on) is only concerned with web portals, and the readers of this article (should be) only concerned with two types of portals: portals that succeed and portals that fail. No one purposely goes out to build a portal that will fail, yet it happens time and time again. To understand some of the key reasons portals fail, it will probably help to know a little bit about how portals evolved to what they are today.

This article describes a set of techniques that you can use to add additional function to a BIRT report beyond the function that is provided by the standard BIRT report designer.

On the average Web page, users have time to read at most 28% of the words during an average visit; 20% is more likely.

The 1% of websites that don't suck can be made even better by strengthening exceptional user performance, eliminating miscues, and targeting company-wide use and unmet needs.
