There are three ways to create custom error pages that are described below.


Define error pages in web.xml

The standard webapp configuration file located in <webapp>/WEB-INF/web.xml can be used to map errors to specific URLs with the <error-page> element. This element creates a mapping between the error-code or exception type to the location of a resource in the web application.

  • error-code - integer value
  • exception-type - fully qualified class name of a Java Exception type
  • location - location of the resource in webapp relative to the root of the web application. Value should start with "/".

Error code example: {code:xml} <error-page>


</error-page> {code} Exception example: {code:xml} <error-page>


</error-page> {code}

h2. 2. context file configuration.

Context files are nomrall located in <jetty.home>/contexts/?.xml (see [ContextDeployer] for more detail). Context files can be used to configure the default error handler provided for a context with more flexibility than is available with web.xml, specifically with the support of error code ranges: {code:xml} <?xml version="1.0" encoding="ISO-8859-1"?> <!DOCTYPE Configure PUBLIC "-//Mort Bay Consulting//DTD Configure//EN" "http://jetty.mortbay.org/configure.dtd">

<Configure class="org.mortbay.jetty.webapp.WebAppContext">

 <Set name="contextPath">/test</Set>
 <Set name="war">
   <SystemProperty name="jetty.home" default="."/>/webapps/test
 <Get name="errorHandler">
   <Call name="addErrorPage">
     <Arg type="int">404</Arg>
     <Arg type="String">/jspsnoop/ERROR/404</Arg>
 <Get name="errorHandler">
   <Call name="addErrorPage">
     <Arg type="java.lang.Class">java.io.IOException</Arg>
     <Arg type="String">/jspsnoop/IOException</Arg>
 <Get name="errorHandler">
   <Call name="addErrorPage">
     <Arg type="int">500</Arg>
     <Arg type="int">599</Arg>
     <Arg type="String">/dump/errorCodeRangeMapping</Arg>

</Configure> {code}

h2. 3. Custom error handle class.

A context may be configured with a custom error handler class that extends [ErrorHandler
