Introduction

jetty-env.xml is an optional Jetty configuration file that you can place in your webapp's WEB-INF directory to configure JNDI resources specifically for that webapp. 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-env.xml configuration file. For a more in-depth look at the syntax, see jetty.xml Syntax Reference.

At startup, Jetty will automatically look for a file of this name in the webapp's WEB-INF directory, and set up the webapp's naming environment so that naming references in the WEB-INF/web.xml file can be resolved from the information in the WEB-INF/jetty-env.xml file (along with any global naming resources defined in a jetty.xml startup file.

Root Element

jetty-env.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" "http://www.eclipse.org/jetty/configure.dtd">
 
<Configure class="org.eclipse.jetty.webapp.WebAppContext">

</Configure>

Make sure you are applying the configuration to an instance of the proper class
jetty-env.xml configures an instance of WebAppContext, and not an instance of Server


Using jetty-env.xml

Place the jetty-env.xml file into your web application's WEB-INF folder. When Jetty deploys a web application, it automatically looks for a file called WEB-INF/jetty-env.xml within the web application (or WAR), and sets up the webapp naming environment so that naming references in the WEB-INF/web.xml file can be resolved from the information provided in the WEB-INF/jetty-env.xml and jetty.xml files.

jetty-env.xml files contain configuration specific to a webapp. Global naming resources should be defined on the server via jetty.xml.

Example

 <?xml version="1.0"?>
 <!DOCTYPE Configure PUBLIC "-//Mort Bay Consulting//DTD Configure//EN" "http://jetty.mortbay.org/configure.dtd">
 
 <Configure class="org.eclipse.jetty.webapp.WebAppContext">

     <Arg type="java.lang.Double">100</Arg>
     <Arg type="boolean">true</Arg>
   </New>
 
  <!-- Add an override for a global EnvEntry                           -->

     <Arg>wiggle</Arg>
     <Arg type="java.lang.Double">55.0</Arg>
