After months of speculation, Sun Microsystems is expected to formally introduce its Project Orion software at the SunNetwork 2003 Conference next week and lay out exactly how much the integrated software bundle is going to cost. In February, Sun first detailed its strategy to package all of its infrastructure software and then update it on a regular quarterly basis - a plan code-named Project Orion. This week, the software bundle will be introduced as the Java Enterprise System. The Java Enterprise System will include directory server, identity management server, Web server, integration server, messaging, calendaring, instant messaging, portal server, Sun cluster software and a new release of the Sun One application server.
