The xpatch mechanism enables you to split up your web.xml and put the snippets into the block it belongs too. It takes all *.xweb files from src/main/resources/META-INF/cocoon/xpatch and applies them to the generated web.xml file that you will find in target/rcl/webapp/WEB-INF/web.xml.

Here is an example of an xweb file:

<xweb xpath="/web-app" 
      unless="comment()[contains(., 'Xindice XML-RPC Server servlet configuration')]" 
      insert-after="servlet[last()]">

  <!-- XMLDB Block, Xindice XML-RPC Server servlet configuration -->
  <servlet>
    <servlet-name>Xindice</servlet-name>
    <display-name>Xindice XML-RPC Server</display-name>
    <servlet-class>org.apache.xindice.server.XindiceServlet</servlet-class>
    <init-param>
      <param-name>xindice.configuration</param-name>
      <param-value>WEB-INF/xindice.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  
</xweb>

This xweb file adds the Xindice-RPC Server servlet to your web.xml.
