Key to the Java EE 6 Platform: NetBeans IDE 7.1

Oracle’s Geertjan Wielenga has a new article up on otn/java, titled “Key to the Java EE 6 Platform: NetBeans IDE 7.1,” in which he shows how the NetBeans IDE provides the tools, templates, and code generators to support Java EE 6 and its main specifications.

He initially observes that, “When you begin to grasp the breadth and ambition of the Java EE 6 Platform, which covers everything from the model (JPA and Bean Validation), to the controller (EJB and Servlets), to the view (JavaServer Faces), a simple entry point is difficult to find. Enter NetBeans IDE 7.1, which is Oracle’s IDE for the Java Platform, created by the same group of developers who created the Java EE 6 Platform. Here you find tools, templates, and code generators intended to be used in combination with the set of specifications that the Java EE 6 Platform encompasses.”

After offering a tour of the NetBeans IDE 7.1 tools that support Java EE 6, Wielenga ends on a cautionary note:

“While code generators and tools such as those described here are great to help you get your feet wet, a danger is that a lot of code is generated that you don't understand and that you therefore do not know how to debug and maintain. The good news is that far less code needs to be generated in Java EE 6 than before, making it far easier to understand and maintain.

Nevertheless, it is advisable to use tools of this kind intelligently. Start small, focusing on specific APIs. Get to know them via the generated code and then slowly extend the application as you become more familiar with the Java EE 6 Platform. Once you are comfortable with the spec, the tools aim to help you become more productive: combining the leanness of the Java EE 6 Platform with the tools in the IDE, you'll be rapidly creating the core of your application.”

Using Transitions for Animation in Oracle’s JavaFX 2.0

A new article by Java Champion and JavaFX expert, Jim Weaver, titled “Using Transitions for Animation in Oracle’s JavaFX 2.0,” shows developers how to animate their nodes in scenes the easy way, using the JavaFX 2.0 TranslateTransition class. JavaFX comes with its own transition classes, whose purpose is to provide convenient ways to do commonly used animation tasks. The article shows how to use the TranslateTransition class to animate a node, moving it back and forth between two positions in the UI.

From the article:

“JavaFX 2.0 comes with several transition classes (that extend the Transition class) whose purpose is to animate visual nodes in your application. JavaFX also contains many builder classes that provide the ability to express a user interface in a declarative-style. In addition, JavaFX has a powerful property binding capability in which properties may be bound to expressions to automatically keep them updated.”
