   Here are few methods for creating XML error page:
   
   1. web.xml
   
   The standard web application configuration file is in <webapp>/WEB-INF/web.xml could be utilize to map errors to specific URLs with the <error-page> element. This element makes a mapping between the error-code or exception type to the location of a resource in the web application.
   
   • error-code - integrate value
   
   • exception-type – It is fully qualified class name of a Java Exception type
   
   • location - location of the resource in web application relative to the root of the web application. Value should start with "/".
   
   example of Error code:
   
   <error-page>
   
   <error-code>404</error-code>
   
   <location>/jspsnoop/ERROR/404</location>
   
   </error-page>
   
   example of Exception:
   
   <error-page>
   
   <exception-type>java.io.IOException</exception-type>
   
   <location>/jspsnoop/IOException</location>
   
   </error-page>
   
   2. context file configuration.
   
   Context files are nomrally found in <jetty.home>/contexts/?.xml (see ContextDeployer for further detail). Context files can be utilized for configuring the default error handler that is required for a context with more flexibility , available with web.xml,
   
   specifically with the support of error code ranges:
   
   <?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
   
   </Set>

   
   

   <!-- by Code -->
   
   <Get name="errorHandler">
   
   <Call name="addErrorPage">
   
   <Arg type="int">404</Arg>
   
   <Arg type="String">/jspsnoop/ERROR/404</Arg>
   
   </Call>
   
   </Get>

   
   

   <!-- by Exception -->
   
   <Get name="errorHandler">
   
   <Call name="addErrorPage">
   
   <Arg>
   
   <Call class="java.lang.Class" name="forName">
   
   <Arg type="String">java.io.IOException</Arg>
   
   </Call>
   
   </Arg>
   
   <Arg type="String">/jspsnoop/IOException</Arg>
   
   </Call>
   
   </Get>

   
   

   <!-- by Code Range -->
   
   <Get name="errorHandler">
   
   <Call name="addErrorPage">
   
   <Arg type="int">500</Arg>
   
   <Arg type="int">599</Arg>
   
   <Arg type="String">/dump/errorCodeRangeMapping</Arg>
   
   </Call>
   
   </Get>
   
   </Configure>
