Oracle's JDeveloper Update Embraces Modularity
But the big news in this release is a new focus on modularity. It's been 18 months since the last JDeveloper update; during that time Oracle re-architected the IDE's internal framework for plug-ins to comply with the OSGi model. Those changes, originally intended to facilitate OSGi tooling, resulted in serious performance improvements, said Oracle Vice President of Product Management Bill Pataky.
"The goal was to make it easier for third parties to build plug-ins to support JDeveloper, but an interesting side effect has been a dramatic improvement in performance because of the modular nature of the OSGi framework," Pataky said. "Our startup time has been reduced by a factor of two or three. Developers will really feel the difference."
The module-based design principles defined by the OSGi (Open Services Gateway Initiative) have emerged as the defacto means of componentizing enterprise Java.
"I always joke that OSGi is a stackless stack," explained Michael Coté, industry analyst at RedMonk. "Instead of having a huge software stack, like an app server, you break it up into smaller pieces and build up just the components you need -- which contrasts quite a bit with the old way of doing enterprise Java, where you'd start with a giant app server and spend a lot of time whittling down to just what you wanted."
JDeveloper 11g R2 also supports "hot" deployments of applications and components into a running environment -- including integrating with the existing security model and web services. This capability adds to the IDE's relevance to Agile environments.
Support for JSF 2.0 and the Facelets page assembly technology is likely to be another attention getter in this release. JDeveloper users now have a highly visual editing environment for Java EE Web development. Oracle already supported JSF rich-client components in the ADF, but with this release the company has added about 170 Ajax-based components, Pataky said, such as interactive thematic maps.
The new ADF Faces skin editor also makes it easier to change the look and feel of the entire ADF application. The editor is bundled with the IDE, but also offered as a stand-alone tool aimed at "design people" who just want to customize the look of components without mastering a full-fledged IDE, according to the company.
Oracle's ADF is a Java EE framework for building enterprise applications. Duncan Mills, Oracle's senior director of product management, characterizes the ADF as a "productivity framework" for developers that provides an abstracted approach to accessing business services. It's also a tool that Oracle uses extensively internally, Mills said.

Download Sun Java Runtime Environment (JRE) 6 Update 21 Free
Java Runtime Environment is the main supplier of libraries, Java Virtual Machine and of some additional elements to run applications that are written in Java.
Java is an artificial language that is used to receive commands and after that translates them into machine language so that it can be performed by computers.
Java Runtime Environment has two main important add-ons in the likes of Java Plug-in and Java Web Start. Java Plug-in allows application programs to work within almost all web browsers and Java Web Start is a framework that enables users the possibility to run application software straight from the web with the help of a browser.
Java was developed and released by James Goslin as the main element of Sun Microsystems’ Java Platform.
Java software is used by all kinds of devices starting out with phones and computers not so high-tech and finishing with big company servers and supercomputers.
Java Runtime Environment 6 Update 18 is equipped with enhancements on the previous versions and with other errors fixed. You have to keep in mind that JRE doesn’t come equipped with development tools like some debuggers or compilers, if you search for such a tool you should check the Java 2 SDK.
What’s New in 6 Update 21 version :
complete update release number is the 1.6.
