访问其他WEB应用程序

import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
import javax.servlet.http.HttpServlet;

public class OtherContextServlet extends HttpServlet
{
 public void service(HttpServletRequest request,HttpServletResponse response)throws IOException,ServletException
 {
  PrintWriter pwout=response.getWriter();
  ServletContext rootContext=getServletContext().getContext("/");
  if(rootContext!=null)
  {
   pwout.println(rootContext.getRealPath("/")); 
  }
  else
  {
   pwout.println("getServlet failed!");
  }
 }
}

注：要想在某一WEB应用程序中获得其他WEB应用程序的ServletContext 对象，必须 加入红字部分。   <Context path="/it315" docBase="d:\myweb" debug="0" reloadable="true" crossContext="true" >
