This is the story of a Mac application developer (okay - it's about two of them) who set out on a quest to find an application development tool based on Java so his boss would let him develop on the Mac platform, which he loved. There was only one catch - he had to find a tool that was fast. Traditional Java programming was going to take waaaay too long to convert the internal custom programs that had been written in an old 4GL.

Any large Java source base can have insidious and subtle bugs. Every experienced Java programmer knows that finding and fixing these bugs can be difficult and costly. Fortunately, there are a large number of free open source Java tools available that can be used to find and fix defects early in the development life cycle. In this article, we'll look at a few examples of specific uncommon1 or unusual defects that can happen in code and see how different Java static analysis tools detect them.

2008 is going to be an important year for Rich Internet Applications. Most organizations are delivering or planning to deliver Rich Internet Applications; however, at the same time, most IT managers are facing a dilemma: which Rich Internet Application technology and platform to use? The number of different frameworks and libraries is too vast to even consider evaluating a fraction of them.

Sun Microsystems, challenged leaders to rethink traditional education models. On the Massachusetts Institute of Technology's (MIT) campus at a forum titled 'Open For Education,' introduced by Sun's Chairman of the Board of Directors Scott McNealy, the participants discussed how the rise of the global network has lowered barriers to access so that educators and students alike should contribute to and share better educational tools.

Ajax(Asynchronous JavaScript and XML) means many things to many people. However, one thing is certain: To users it implies a higher level of functionality and an improved experience. To the developer, another certainty follows: More work. The only question is how much work and to what end.

Mentality of programmers depends on a programming language or tool they use. Should they even try to learn what's under the hood in a particular framework?

In the second of a new series, Yakov Fain takes a look at the basics of object orientation and method overloading in Java.

Yakov Fain's popular online tutorial series continues. This lesson he discusses the basics of threads, including how to create them, how to get them to step aside, and how to stop them.

Yakov Fain, in Lesson 9 of his immensely popular online 'Java Basics' series for JDJ Industry Newsletter, talks about using threads for creating more advanced programs than those already discussed in Lesson 8. He analyzes the role they play in major Internet portals like Yahoo, CNN, or your bank's Web site. These portals usually display different types of information like News, Weather, Stock Market quotes, etc. Each of these info pieces appears on the screen instantaneously even though it's coming to the portal from different servers.

We'll build a servlet that will demo some new Java 5.0 features and do some basic tasks like creating a session to track user visits to multiple Web pages. This code can easily be extended to store a user ID in the session that will travel with her as the site is navigated. The value of the visit counter is stored in the session so multiple visits to the page will be counted (this includes the page refreshes after pressing the browser's 'Reload' button). If the counter goes over five, the counter gets cleared.

The single thing that Adam Kolawa in 2004 (prophetically) said he'd like to change about Java's history is its separation from Microsoft. 'I think it is a shame that the technologies from both sides cannot be used together,' he says, in an exclusive interview with JDJ. 'Java seemed to be the perfect technology to bring Microsoft into the world of coexistence, and I think this opportunity got lost.'

Developers using Java on clients or in small projects may not believe that there is a fundamental problem with Java's robustness. People working with huge applications and application servers written in Java know about the problem but may doubt that it's possible to build something like an unbreakable Java architecture.

For various reasons, an application may install a security manager. Usually it does so to guard against malicious third-party code either installed or dynamically downloaded at runtime. If the application uses RMI APIs, it's even required by a Java specification that a security manager be installed, otherwise the classloader will not download any classes from remote locations.

In the five years that I have worked in Web solutions practices, a typical business problem has changed from 'we need a new Web site' to 'we need to regain control over our existing sites.' It's not uncommon for large corporations to have hundreds or even thousands of different Web sites spread over various service lines, geographies, and organizational boundaries. This presents challenges ranging from logistical and technical, to creative, business, and legal. This article focuses on solving the problem of ubiquitous navigation across diverse Webscapes.

Language tools such as compilers, interpreters, and code generators are a critical part of the software development landscape. Any software project will include several procured tools and very likely several in-house tools. Experience shows that the only guarantee with such tools is change: the underlying language may change due to improvements or extensions and the functionality provided by the tool expands, driven by user-requested features and the need to stay in front of the competition. The specific changes that will be made are rarely known at the outset, but change is coming.

Application architects have heard about the increased importance of security, but in many cases they really don't know how to approach this issue. In this article, I'll share my experience and define a few basic steps and checkpoints for building application architecture with security in mind.

I'm really jazzed about Java 5.0! We've been treated over the years to incremental improvements in JVM performance. JDK 1.2 brought us the collections framework as well as Swing, the thread context class loader, and improvements in RMI. JDK 1.3 and 1.4 continued in the same vain with logical improvements to libraries, JVM enhancements, and performance upgrades. Although this article doesn't intend to take trip down memory lane, it's important to understand that Java 5.0 brings a truly remarkable and rich set of new tools to our programming landscape as compared to other JDK releases.

Pattern matching using 'regular expressions' can help automate a number of text-processing operations like search and replace, input validation, text conversion, and filters. What otherwise requires significant amounts of code can be done in just a few lines with regular expressions because of the powerful underlying regular expressions processing engine.

Are your Java programs littered with a multitude of randomly placed System.out.println statements and stack traces? When you add debugging messages to a class in a project, are the outputs of your messages interleaved among dozens of messages from other developers, making your messages difficult to read? Do you use a simple, hand-rolled logging API, and fear that it may not provide the flexibility and power that you need once your applications are in production?

This article describes how to host an ActiveX/.NET control in a Java application that is targeted for the Microsoft Windows Platform. I'll assume you know the fundamentals of Java, C++, JNI (Java Native Interface), Win32, COM (Component Object Model), and ATL (Active Template Library).

'Ease of Development' is one of the main focuses in J2SE 5. Accordingly, J2SE 5 introduces several new features designed to simplify the developer's life. If you use these new constructs, your code will become more compact and expressive, hence easier to understand and debug. This article explains how you can use the new features to prevent some silly mistakes, as well as some that are not so silly.

Enterprises for the first time have the ability to deploy wired and wireless security access on a per user basis, with Aruba Wireless Networks' grid security controllers.

Java's implementation of Remote Method Invocation (RMI) is easy to use and powerful. Java makes setting up an RMI server an almost trivial task because the JVM handles complex tasks such as networking and object serialization. Once running, connecting client applications to the RMI server is also a breeze.

You know how to write good Java code and deployment to a server is no mystery either. But have you ever had to work in large development teams, maybe geographically dispersed (off-shoring...)? Ever had to address the pain of application software updates?

Have you looked at the certificate that your neighbor has so proudly displayed in his or her office? Have you ever wondered if getting certified in Java is worth the time and effort?

These days Calvin Austin is one of the busiest people in the Java world: J2SE 5.0, that was also known as the 'Tiger' project, is being officially released today! JDJ's Yakov Fain was able to catch Austin, spec lead for Java 5.0, right before the plane from San Francisco to New York where he'll today be presenting the new features of the Java language to the New York Java Users Group.

Those familiar with the java.util.Comparator interface of the Java API realize its capabilities for sorting a collection of objects based on an attribute of the objects in the collection. This works well when there is only a single field in which sorting is required. When more complex sorting is necessary, the limitations of sorting on a single field become obvious.

Though most Java developers think of the Java Native Interface (JNI) as a framework for developing native libraries that can be called from Java, relatively few know that JNI also supports communication in the reverse direction: it provides native programs written in C with the ability to call Java objects. However, the coding is thorny; logic that can be coded readily in a few lines of Java requires several times more lines of C, thanks to JNI's granular programming model and peculiar approaches to exception handling and garbage collection.
