Originally developed in the Sydney suburb of Balmain by software engineer Greg Wilkins, Jetty was originally a HTTP server component of Mort Bay Server (Mort Bay is an area of Balmain.)
Jetty was originally called IssueTracker (its original application) and then MBServler (Mort Bay Servlet server). Neither of these were much liked, so Jetty was finally picked.
Jetty was started in 1995 and was hosted by MortBay, creating version 1.x and 2.x, until 2000. From 2000 to 2005, Jetty was hosted by sourceforge.net where version 3.x, 4.x, and 5.x were produced. In 2005, the entire Jetty project moved to codehaus.org. As of 2009, the core components of Jetty have been moved to Eclipse.org, and Codehaus.org continues to provide integrations, extensions, and packaging of Jetty versions 7.x and 8.x (not 9.x)
