可以试一试调用Windows API

to handsomeghost(方鸿渐) 那样程序的移植性不就受到影响了？

<%@ page import="java.io.*" %>

<%
Runtime runtime = Runtime.getRuntime();
Process process =null;
String line=null;
InputStream is =null;
InputStreamReader isr=null;
BufferedReader br =null;
String ip="你要ping的ip";
//自行修改上面的ip位址
try
{
process =runtime.exec("ping "+ip);
is = process.getInputStream();
isr=new InputStreamReader(is);
br =new BufferedReader(isr);
out.println("<pre>");
while( (line = br.readLine()) != null )
{
out.println(line);
out.flush();
}
out.println("</pre>");
is.close();
isr.close();
br.close();
}
catch(IOException e )
{
out.println(e);
runtime.exit(1);
}
%>

根据返回的字符传来判断网络是否连通
