Fred Domke points out to me that Sun Microsystems released news late Sunday that it will publish the source code for Java System Application server software Platform Edition 9.

From Yahoo news:

The move by Sun comes almost two weeks after the company published the source code for its Solaris operating system that is used to run large computer centers. That move also, Sun hopes, will help drive sales of its software, services, as well as its computer servers and possibly its data storage gear.

...

"Now I can sell services, systems, storage and design services, because I got my foot in the door" by giving away the code to the Java application server, John Loiacono, the head of Sun's software group, said in a telephone interview.
