Java jives with Linux, open source

With Java and open source technology now as intertwined as they are, it's no surprise that many announcements out of last week's JavaOne conference in San Francisco had either a Linux or an open source slant.

Sun, the sire of Java, celebrated the technology's 10th year by announcing that two of its Java-focused application server platforms will be released as open source, free software. Sun says its Java System Application Server Platform Edition 9.0 as well as its Java System Enterprise Server Bus (ESB) product will become free software.

The Java System Application Server is software for developing XML-based Web services software in Java, and the ESB product is used for running the applications. These two platforms join the free code category with Sun's own Solaris operating system, which was released to the open source community last month.

In addition to the Sun news, open source application server rival JBoss also announced a partnership with Sun rival HP, where JBoss' Application Server (AS) is now certified to run with HP's Linux Reference Architecture, a blueprint for how software and hardware should interact on HP servers.

JBoss AS is certified to run on HP ProLiant and Integrity servers, and the partnership will give HP engineers access to JBoss engineering resources to make the AS platform and HP Linux servers run together more smoothly out of the box, the vendors say.

One interesting fact brought up at JavaOne was the shift in Java deployments: 708 million of the 2.5 billion Java-based devices deployed worldwide are cell phones. Along those lines, Motorola launched its latest Java-based E895 smartphone, which runs on a mini Linux platform. The second in a line of Java- and Linux-based handsets from Motorola, the new gadget includes a music player, a camera (of course) as well as support for Bluetooth connectivity to such a wide range of peripherals as headsets to printers. (Motorola says the phone can make calls too.)
