Sun to add Jxta to Sun Grid Engine June 13, 2003 — Sun Microsystems this week unveiled an upgrade to its Jxta open source peer-to-peer technology, version 2.1, featuring metering of peer network traffic. In addition to the new release, Sun may add Jxta to other products such as Sun Grid Engine, which provides grid services, said Juan Carlos Soto, Sun group manager for Project Jxta.“Jxta is a nice discovery [mechanism] to let you discover when computers are available and then incorporate them into your grid,” Soto said.Jxta works across the Internet and can traverse firewalls, with permission. Sun with the 2.1 version of Jxta this week for Java 2 Platform, Standard Edition (J2SE) added metering and monitoring, enabling the inspection of traffic and memory usage on a network peer, and querying of remote peers for this information.Available this week for free download, version 2.1 also features enhanced communications, including verified packet delivery to a peer. Also added is support for the sockets paradigm for network programming.Also at JavaOne on Thursday, James Gosling, vice president of Sun Labs and a Sun fellow, in a press breakfast stressed that Sun with tools such as Project Rave wants to get past the complexity that has been endemic to Java. “This war against complexity is a complete constant,” said Gosling, who Sun calls the Father of Java.Java is good for building complex systems but has been complex itself, he said. He contrasted the situations with Java with what Microsoft offers with .Net.“.Net makes the easy things easy and the hard things impossible,” Gosling said. “For us, hard things are possible and the easy things are tough Paul Krill is an InfoWorld editor at large.
