The information below has been kept as is for historical reasons for folks running old versions like Jetty 6.
The Jetty projects has was started in 1995 and since then has been associated with many names and brands:
Jetty was the name initially given to the HTTP server component from Mort Bay. The name Jetty has now grown to encompass the suite of components which includes a HTTP server, HTTP client, javax.servlet container, the hightide application server and many other related components and utilities. Jetty is now the name of the encompassing projects at mortbay(v1-v4), sourceforge(v5), codehaus(v6-) and eclipse(v7-).
The Java HTTP server that became jetty was originally developed in 1995 by Greg Wilkins of Mort Bay Consulting as part of an issue tracking application. Versions 1.x through to 6.1.x of jetty were developed under org.mortbay packaging and Mort Bay still holds the major part of the copyright on the jetty code base. Mort Bay directly hosted the jetty project until version 3.x and was the prime sponsor of development until 6.x.
The role of Mort Bay in leading the development of Jetty was taken over in 2006 by Webtide LLC, an open source services company that employs many of the jetty contributors.
From 2000 to 2005, the jetty project was hosted at sourceforge.net where versions 3.x, 4.x and 5.x were produced.
In 2005, the jetty project moved to the codehaus for its hosting services and open source community. In 2009, after the core components of Jetty moved to eclipse, the jetty @ codehaus project continues to provide integrations, extensions and packaging of jetty.
In 2009, the Jetty project moved it's core components to be a project of the Eclipse Foundation, in order to improved IP processes and broaden the licensing and community of the project.
