Below is from the NetBeans homepage to provide a high level view of NetBeans IDE 6.8
The NetBeans project is supported by a vibrant developer community and offers extensive documentation and training resources as well as a diverse selection of third-party plugins.
Release OverviewNetBeans IDE 6.8 is the first IDE to offer complete support for the entire Java EE 6 spec with improved support for JSF 2.0/Facelets, Java Persistence 2.0, EJB 3.1 including using EJBs in web applications, RESTful web services, and GlassFish v3. We also recommend it for developing with the latest JavaFX SDK 1.2.1, and for creating PHP web applications with the new PHP 5.3 release or with the Symfony Framework.
Our unique integration of Project Kenai, a collaborative environment for hosting open-source projects, now comes with full JIRA support, and improved instant messenger and issue tracker integration. We also added features to the IDE's Maven and database integration, and improved the editor and tools integration of Ruby, Groovy, and C/C++ projects.
