Sun open sources Java system Content Delivery Server

February 2007

Sun Microsystems is adding yet one more piece of its Java Enterprise System to open source. The product is the Content Delivery Server, a product that came to Sun through its 2003 Pixel acquisition.

Like the other pieces of JES, Sun will offer two versions: the existing commercial product, which will have regular Sun support, and an open source version. CDS is aimed at entities that are selling content, and not necessarily at corporate end users, meaning this is a bid by Sun to draw more third-party support.
CDS is a mobile content delivery and management platform originally aimed at wireless carriers. In the four years that Sun has owned CDS, it has drawn 14 customers, 13 of which are telcos.
Sun characterises CDS as a vending machine type of system, in that it stocks add-ons that wireless carriers can sell to subscribers on demand. It said a new market is starting to emerge with content providers who might open a direct channel to wireless subscribers by bypassing the carriers.
At this point, Sun will offer CDS under the same Mozilla-derived Common Development and Distribution License that it has used for Java EE and other offerings, rather than the more popular General Public License. For Sun, the attraction of CDDL is that it is much looser than GPL and does not require contribution of derivative work back to the community.
Just as Sun eventually opened Java ME and SE to GPL, it might eventually do the same with CDS, according to David Bryant, senior marketing director for infrastructure software products.
