Configuring jetty consists of building a network of connectors and handlers and providing their individual configurations. It is a combination of
- HTTP server configuration (ports, thread pools, buffers, etc.)
- Web container configuration (webapps deployment, security realms, JNDI etc.)
- Web application (init parameters, non standard options, etc.)
See Jetty Architecture for a graphical representation of the interactions among connectors and handlers.
Since Jetty components are simply Plain Old Java Objects (POJOs), you can accomplish this assembly and configuration of Jetty by a variety of techniques:
See the examples in the Jetty 7 Latest Source XRef.
Using Jetty XML
The default configuration file for Jetty is jetty.xml, typically located at $JETTY_HOME/etc/jetty.xml. Usually jetty.xml configures these components:
- the Server class (or subclass if extended) and global options
- a ThreadPool (min & max thread)
- connectors (ports, timeouts, buffer sizes, protocol, etc.)
- the handler structure (default handlers and/or a contextHandlerCollections, etc.)
- the deployment manager that scans for and deploys webapps and contexts
- login services that provide authentication checking.
- a request log
Not all Jetty features are configured in jetty.xml. There are several optional configuration files that share the same format as jetty.xml and, if specified, concatenate to it. These configuration files are also stored in $JETTY_HOME/etc/, and examples of them are in svn. start.jar selects the configuration files to use. jetty.xml usage describes the process of merging configuration files.

Because Jetty configuration can be considered as calling setters on a collection of POJOs, regardless of the actual method used, the apidocs are the ultimate resource for configuration.
