jetty-web.xml is a Jetty configuration file which can be bundled with a specific web application. The format of jetty-web.xml is the same as jetty.xml -- it is an XML mapping of the Jetty API.

This document offers an overview for using the jetty-web.xml configuration file. For a more in-depth look at the syntax, see Syntax Reference.

Root Element

jetty-web.xml is applied on a per-webapp basis, and configures an instance of org.eclipse.jetty.webapp.WebAppContext.

<?xml version="1.0"  encoding="ISO-8859-1"?>
<!DOCTYPE Configure PUBLIC "-//Mort Bay Consulting//DTD Configure//EN" "">
<Configure class="org.eclipse.jetty.webapp.WebAppContext">

Make sure you are applying the configuration to an instance of the proper class. jetty-web.xml configures an instance of WebAppContext; jetty.xml configures an instance of Server.

Using jetty-web.xml

Place the jetty-web.xml into your web application's WEB-INF folder. When Jetty deploys a web application, it looks for a file called WEB-INF/jetty-web.xml or WEB-INF/web-jetty.xml within the web application (or WAR) and applies the configuration found there. jetty-web.xml is called after all other configuration has been applied to the web application.


The distribution contains an example of jetty-web.xml inside the WEB-INF folder of the test webapp war ($JETTY_HOME/webapps/test.war/WEB-INF/jetty-web.xml).
