Setting up the classpath
To run Jetty, you need only these jars:
Those jars give you the ability to serve web applications.
If you wish to use JSPs, then you will need a couple of additional jars.
JSP 2.0 is used with version 2.4 of the servlet specification. Depending on the functionality you require, you may be able to use this version rather than the newer JSP2.1 jars.
This is the jsp version mandated by servlet specification 2.5. You will need these jars:
You need to use J2SE5 (aka jdk 1.5) if you wish to use JSP2.1.
The jetty configuration files (eg jetty.xml) have an xml syntax that is a straightforward mapping of the java API. Take a look at the files in etc/ for some hints on what calls to make in your own code. Here's the minimal code to set up a Jetty server and webapp:
Using Jetty with Servlets (but not webapps)
Have a look at what is going on near the bottom of the etc/jetty.xml file where it says: "Configure a context directly - no XML parser required". This is setting up a ContextHandler that can serve servlets and static content. The servlet setup isn't done by a web.xml file, but rather in API calls instead. The DefaultServlet impl is used to serve static content. If you just want to serve static content, then you might have to create your own Handler using the DefaultServlet implementation as a guide.
