Sun's Open Source Java Moves Are Bold, Smart, and Limited

Sun also announced that the Java Enterprise Edition platform would be released under GPLv2 through their GlassFish project, which is Sun's own Java EE application server that more-or-less competes against application servers such as Red Hat's JBoss and IBM's WebSphere. GlassFish was already available as open source under Sun's CDDL license, and it's not clear that releasing it under GPL will help GlassFish grow into a full-service Java EE platform, but it certainly doesn't hurt.
