Jetty is a 100% Java HTTP Server and Servlet Container.
This means that you do not need to configure and run a
separate web server (like Apache) in order to use java,
servlets and JSPs to generate dynamic content. Jetty is
a fully featured web server for static and dynamic content.
Unlike separate server/container solutions, this means
that your web server and web application run in the same
process, without interconnection overheads and complications.
Furthermore, as a pure java component, Jetty can be simply
included in your application for demonstration, distribution
or deployment. Jetty is available on all Java supported
platforms. Jetty-eclipse is a subset of fully jetty needed
to run Eclipse.
