New in Java EE 6 SDK Update 4:
GlassFish Server Open Source Edition provides a server for the development and deployment of Java EE applications and web technologies. The Java EE 6 SDK Update 4 bundles include GlassFish Server Open Source Edition 3.1.2 distributions. Those distributions implement Java EE 6 technologies.
Java EE 6 introduces the concept of profiles. A profile is a collection of Java EE technologies and APIs that address specific developer communities and application types. The following profiles are implemented through the GlassFish Server distributions:
The following resources will help you get started with GlassFish Server Open Source Edition and make the most of its capabilities.

index.htmlfile in that location for more information about the samples.
Java EE 6 SDK Update 4 distributions require a minimum of 200 Mbytes of free disk space to install, and 100 Mbytes of free memory to run. The following table lists supported operating systems and provides minimum memory, recommended memory, minimum disk space, recommended disk space, and Java virtual machine (JVM) for each.
Ensure that the required JDK software is installed on your system and that the JAVA_HOME environment variable points to the JDK installation directory, not the Java Runtime Environment (JRE) software.
For Mac OS X systems, the SDK uses the JDK that is part of the Macintosh operating system. However, OS X Lion does not provide a Java runtime by default. If necessary, obtain the required JDK version from the Apple Support Downloads site. (Search for the term "Java SE".)
|ID||Description / Workaround|
|12652086||Java EE 6 Samples should not be used as a template for production code |
Sample code in the Java EE 6 Samples has been provided to assist developers in understanding Java functionality. This code has been deliberately simplifiedand does not take security considerations into account. For this reason, it should not be used as a template for any production code.
