• Interacting with Databases through the Java Persistence API 12 months ago
  
  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.
• Bug fixes for Java on OS X 1 year, 1 month ago
  
  Everyone knows that Mac is safer than Windows because almost all malicious software targets Windows. But every rule has exceptions, and in this case, the exception has been Java.
• Using Prototype Property in JavaScript 1 year, 3 months ago
  
  In this article by Stoyan Stefanov, you'll learn about the prototype property of the function objects. Understanding how the prototype works is an important part of learning the JavaScript language. After all, JavaScript is classified as having a prototype-based object model. There's nothing particularly difficult about the prototype, but it is a new concept and as such may sometimes take some time to sink in. It's one of these things in JavaScript (closures are another) which, once you "get" them, they seem so obvious and make perfect sense. As with the rest of the article, you're strongly encouraged to type in and play around with the examples; this makes it much easier to learn and remember the concepts.
• Book review: Java Power Tools 1 year, 4 months ago
  
  An IDE is only the first and most obvious component of a complete development environment. There are build tools, source control, unit testing frameworks and a whole bunch of other tools that together make up the software development eco-system. It is this diverse and interlocking set of tools that is the focus of Java Power Tools, rather than this or that IDE (NetBeans or Eclipse, for example).
• Sun sheds light on its open-source future 1 year, 4 months ago
  
  "Sun UK's chief open-source officer, Simon Phipps, has a high-profile role to play as the company aims to complete its move to 100 percent open software development. Echoing the words of James Gosling, the father of the Java programming language, Phipps said that, after more than a decade of Java development, the time is right for "the next chapter" in software programming ....

• TechBookReport on 'Groovy Recipes' 1 year, 5 months ago
  
  Now that Java platform is being recognised as a key asset to be exploited by programming languages other than Java, we've seen a flurry of activity in the area of dynamic/scripting languages. While JRuby has had plenty of support from Sun - including significant levels of support from NetBeans - there is also plenty of interest from in the Groovy programming language. For many Java developers the progression to Groovy rather than Java makes a lot of sense - the language has been expressly designed to make the most of a developer's existing Java skill set. And, for those looking for a good introduction there's the very wonderful 'Groovy In Action' to draw upon.
• Microsoft to Help Eclipse 1 year, 8 months ago
  
  In a surprise announcement, Microsoft says it will work with the Eclipse Foundation on Java/Windows interoperability.
• Sun will make Java work for iPhone 1 year, 8 months ago
  
  The company will make Java Virtual Machine available by June to enable Java apps for Apple's smartphone.
• TechBookReport on 'Next Generation Java Testing' 1 year, 10 months ago
  
  Most technical books fall into one of two categories: either extolling a particular language, framework or tool or else a book on a particular process, development technique or theory. In the case of 'Next Generation Java Testing' we've got a book that does a bit of both. On the framework side of things the book looks at TestNG, a Java testing framework that goes beyond the current de facto choice of JUnit. And on the process side of things we have a book that dares to suggest that there are limitations in the whole idea of unit-testing in the context of Test-Driven Development.
• TechBookReport on 'Tomcat: Definitive Guide' 1 year, 10 months ago
  
  Tomcat is the world's most popular Java servlet and JSP container, without question. It's a key part of the open source stack that powers many web applications - both in the enterprise and on the internet. However, if we're honest getting Tomcat installed, configured and tuned is no easy task in many cases, particularly for more complex applications. Tomcat: The Definitive Guide aims to be just that, the definitive guide to all aspects of Tomcat installation, configuration and administration. Specifically the book covers Tomcat 5.5 and Tomcat 6.0, though the latter is recommended by the authors and gets most of the attention.
• Open source Java could result in port to iPhone 2 years ago
  
  "With the first anniversary of open-source Java this week, a Sun Microsystems Inc. official said he believes the project could bear a sought-after fruit in the Java community: the porting of Java to Apple Inc.'s iPhone..."
• Reduce lock contention and improve performance 2 years, 1 month ago
  
  The IBM Lock Analyzer for Java, available from alphaWorks, provides real-time lock monitoring on a running Java application. It highlights threads suffering from lock contention that could be hurting application performance. This article introduces the IBM Lock Analyzer for Java, explains the architecture on which it is built, and provides some thoughts about the tool's future direction.
• TechBookReport on 'Scripting In Java' 2 years, 1 month ago
  
  While Java the programming language may not be the hot topic it once was, Java the platform is coming increasingly to the fore. And, at the forefront of this are the dynamic languages that make full use of the Java Virtual Machine (JVM): Jython, JRuby, JavaScript, Groovy and the like, as well as the old stalwart and pioneer Beanshell (written by Pat Niemeyer of Learning Java fame). With dynamic JVM languages flowering all over the place, Scripting In Java is a timely little book for those hoping to get to grips with the topic.
• Speed up developing Rich Internet Applications using OpenSwing and Spring 2 years, 1 month ago
  
  OpenSwing is an opensource library of advanced Swing components, including a powerful grid control, that can be used, as the other controls, directly in the UI designer of the IDE: grid control and grid columns can be added using the UI designer and their properties can be defined using the properties inspector too. All controls are binded to POJO objects and data binding mechanism is provided to both grids and Form panels of controls. Supported IDEs are NetBeans, JDeveloper (untuil 2006 version), Eclipse (using Window Builder plugin) and JDeveloper. Using OpenSwing it is possible to develop both Desktop applications and Rich Internet Applications, i.e. two tier and three tier applications. Spring, Hibernate and iBatis integration with OpenSwing is available too.
