Section 6.4 Setting Up the Class Path
To run Jetty, you need only the following jars on the classpath:
servlet-api-2.5-6.x.jar
jetty-util-6.x.jar
jetty-6.x.jar
This gives you the capability to handle HTTP with handlers, servlets and web applications.
Additional features such as JSP and AJP require additional jars (normally found in subdirectories of $JETTY_HOME/lib).
