Introduction to JRockit JDK
The BEA JRockit JDK provides tools, utilities, and a complete runtime environment for developing and running applications using the Java programming language. The BEA JRockit JDK also includes the BEA JRockit Java Virtual Machine (JVM). The BEA JRockit JVM is developed and optimized for Intel architectures to ensure reliability, scalability, and manageability for Java applications.
This section contains information on the following subjects:
The BEA JRockit JVM (see the Compatibility Between Releases for information on BEA JRockit versions) is a high performance JVM developed to ensure reliability, scalability, manageability, and flexibility for Java applications. The BEA JRockit JVM delivers a new level of performance for Java applications deployed on Intel 32-bit (Xeon) and 64-bit (Xeon and Itanium) architectures at significantly lower costs to the enterprise. Furthermore, it is the only enterprise-class JVM optimized for Intel architectures, providing seamless interoperability across multiple hardware and operating system configurations. BEA JRockit JVM makes it possible to gain optimal performance for your Java applications when running it on either the Windows or Linux operating system platforms on either 32-bit or 64-bit architectures.
For more information on JVMs in general, see the Introduction to the JVM specification at:

The BEA JRockit JVM is one component of the BEA JRockit Java development kit (JDK). Along with the BEA JRockit JVM, this kit is comprised of the Java Runtime Environment (JRE), which contains the JVM and Java class libraries (as specified by the Java 2 Platform API Specification), along with a set of development tools, such a compiler, a debugger, and so on.
