Sun Opens Source on Java

Sun Microsystems Inc. (Nasdaq: SUNW) today took another step down the open source road, by opening up the source code for its Java System Application Server and its Java System Enterprise Server Bus (see Sun Open Sources Key Java Techs).

To further underline its commitment, Sun is also donating 135,000 lines of source code from its Sun Java System Instant Messaging and Sun Java Studio Enterprise products for use by the open source community.

This is Suns second major foray into open source in recent months. Earlier this year, the vendor made the source code for the latest version of its Solaris operating system, Solaris 10, available under the Common Development and Distribution License (CDDL). (See Sun Opens Solaris and Sun Hits the Source.)

By opening up both Solaris and the Java technologies, Sun is attempting to lure more and more developers onto the platforms and create a groundswell of support. Like open-source Solaris, the Java products will also be available under the CDDL.

Why the sudden interest in open source? “Sun has had its back up against a wall for a while now,” says Roger Kay, vice president of client computing at IDC. “This is them trying to get back in the game essentially.”
