从Request对象中可以获取各种路径信息，以下例子：

假设请求的页面是index.jsp,项目是WebDemo，则在index.jsp中获取有关request对象的各种路径信息如下

String path = request.getContextPath();String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";String remoteAddress=request.getRemoteAddr();String servletPath=request.getServletPath();String realPath=request.getRealPath("/");String remoteUser=request.getRemoteUser();String requestURI=request.getRequestURI(); out.println("path:"+path+"<br>");out.println("basePath:"+basePath+"<br>");out.println("remoteAddr:"+remoteAddress+"<br>");out.println("servletPath:"+servletPath+"<br>");out.println("realPath:"+realPath+"<br>");out.println("remoteUser:"+remoteUser+"<br>");out.println("requestURI:"+requestURI+"<br>");

结果：

path:/WebDemo
basePath:http://localhost:8683/WebDemo/
remoteAddr:127.0.0.1
servletPath:/index.jsp
realPath:D:\apache-tomcat-6.0.13\webapps\WebDemo\
remoteUser:null
requestURI:/WebDemo/index.jsp
