jetty.xml is the default configuration file for Jetty, typically located at $JETTY_HOME/etc/jetty.xml. Usually the jetty.xml configures:
- 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 provides 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. The selection of which configuration files to use is controlled by start.jar and the process of merging configuration is described in jetty.xml usage.
jetty.xml configures an instance of the Jetty org.eclipse.jetty.server.Server.
<?xml version="1.0"?> <!DOCTYPE Configure PUBLIC "-//Jetty//Configure//EN" "http://www.eclipse.org/jetty/configure.dtd"> <Configure id="Server" class="org.eclipse.jetty.server.Server"> ... </Configure>
$JETTY_HOME/etc contains the default jetty.xml, as well as other sample configuration files (jetty-*.xml) which can be passed to the server via the command line.
