Java 2 For Linux

Sun is delivering two of its Java 2 platforms on Linux, further extending Java technology's ubiquity across all major platforms. Specifically, Java 2 Enterprise Edition (J2EE) v 1.2.1 and the fastest client side Java platform to date, Java 2 Standard Edition (J2SE) v 1.3, are shipping and are available in beta for Linux.

In addition to its own delivery of Java 2 for Linux, Sun also announced a new distribution agreement that will deliver Java and Linux together to developers. MandrakeSoft will redistribute Java 2 Standard Edition (J2SE) v 1.2.2 for Linux. The delivery of the Java 2 platform on Linux enables Linux developers to write and deploy innovative enterprise applications, based upon Java, to Linux systems.

"Linux developers are keenly aware that Java technology delivers the powerful and productive programming environment they require: cross-platform deployment and secure, robust features. Therefore, we focus large attention toward ensuring the Java 2 platform reaches Linux developers," said Rich Green, Sun's vice president of Java Software Development. "Our agreement with MandrakeSoft will complement our existing distribution strategy. This, along with our own delivery of Java ports for Linux, illustrates how serious we are about keeping Java technology alive and well across all major platforms."

Java 2 Enterprise Edition on Linux

Java 2 Enterprise Edition (J2EE) v 1.2.1, now available on Linux, enables businesses to protect and leverage existing infrastructure investments by linking existing enterprise systems with new web-based applications. J2EE greatly simplifies enterprise application development, providing customers with faster time to market and the freedom to choose among best-of-breed, compatible enterprise solutions. Two core components of J2EE, Enterprise JavaBeans architecture and JavaServer Pages, are widely adopted and industry tested. These technologies, along with the port for eXtensible Markup Language (XML), extend Java computing into the enterprise-class arena. J2EE v 1.2.1 is also available on Solaris 7 and 8 and Windows NT and 2000. J2EE has already been licensed by over a dozen companies, including BEA, Oracle and Art Technology Group.

Java 2 Standard Edition on Linux

Sun's fastest client-side Java platform to date, J2SE version 1.3, includes a port to Linux currently in beta stage. J2SE v 1.3 for Linux also includes both the Java HotSpot Client VM and Java HotSpot Server VM. When compared to the initial release of J2SE for Linux, version 1.3 is expected to dramatically improve performance in several areas: startup time, memory footprint, and overall usability. The improved performance is due in part to the new Java HotSpot Virtual Machines as well as library tuning throughout the platform, particularly in the Java Foundation Classes. J2SE v 1.3 for Linux is expected to ship later this year. Sun began shipping a Linux version of J2SE, version 1.2.2, in February of this year. This Linux version of J2SE incorporates significant contributions from Blackdown, a non-profit organization of Java technology and Linux developers.

J2SE for Linux is freely available via download for individual use:

The associated Java runtime environment for Linux, which enables users to run Java-based applications, is freely redistributeable per the terms of the license.

Source code is also available through Sun's Community Source Licensing program (SCSL):

Furthering its commitment to work with the Java community on future Java software development, Sun also submitted the next versions of Java 2 Enterprise Edition v. 1.3 and Java 2 Standard Edition v 1.4 to the Java Community Process Program in February.

Expanded Distribution: Java Technology and Linux

An agreement between Sun and MandrakeSoft will result in the distribution of Java 2 Standard Edition (J2SE) v 1.2.2 for Linux, providing developers additional opportunities to combine the power of Java with the popular operating environment.

Sun and Caldera Systems announced in February that Caldera began shipping J2SE technology v 1.2.2 and plans to ship Java HotSpot Client and Server Virtual Machines to its enterprise-focused Linux developer community later this year. Caldera is the first commercial Linux distribution vendor to license Java technology source code from Sun.

Through these distribution agreements Sun, MandrakeSoft, and Caldera Systems are providing the most current Java technology to the Linux community. The union of the Java 2 platform with Linux greatly expands the pool of enterprise applications available to Linux developers, and it immediately enables Linux end-users to take advantage of thousands of Java-based applications. The Java 2 platform is the feature complete, stable, secure platform for network-centric computing.

"We are very proud to ship Java technology with our new Linux-Mandrake 7.1. We have included the Java 2 Platform SDK, Standard Edition because it provides Linux developers and users with a thriving technology. At a moment when Linux is gaining more and more acceptance in the market place, this state-of-the-art technology package enables users, developers, and enterprises access to a large number of high-end applications and tools," said Jacques Le Marois, President of MandrakeSoft.

Linux joins numerous other existing operating systems that support the Java 2 platform, including operating systems from Sun, IBM, Compaq, HP, Microsoft, Apple, Novell, SCO, and BE.
