Configuring ActionServlet in web.xml File

There are two ways that ActionServlet can be configured to receive requests in web.xml.

·          First, ActionServlet can be configured using path mapping, as shown here: Path mapping routes to ActionServlet all requests that match a specified path.
 The default path is /do/*. action org.apache.struts.action.ActionServlet config /WEB-INF/struts-config.xml 1 action /do/*

·         The second way to map requests to ActionServlet is to use extension mapping. Extension mapping maps to ActionServlet all requests with the specified extension.
The default extension to use is *.do action org.apache.struts.action.ActionServlet config /WEB-INF/struts-config.xml 1 action *.do
