PS：这两天在看java的东西，顺便总结两个JSP环境信息探针，做了一些修改。UTF-8编码，在linux下直接复制保存为xxx.jsp就可以，win中文版里面默认编码是gb码，建议用文本编辑器另存为UTF-8编码，否则可能显示乱码。
第一个如下：
<%@page contentType="text/html;charset=UTF-8"%>
<%@page import="java.io.*,java.util.*,java.net.*" %>
<%!
String tblWidth = "700";
String tblAlign = "center";
String strOS =System.getProperty("os.name");
private String getIp()
{
String strTmp="";
try
{
strTmp =InetAddress.getLocalHost().getHostAddress();
return strTmp;
}
catch(Exception e)
{
return strTmp;
}
}
private String getSystemEnv() throws Exception
{
String OS = System.getProperty("os.name").toLowerCase();
StringBuffer sb=new StringBuffer("");
Process p=null;
if(OS.indexOf("windows")>-1)
{
p=Runtime.getRuntime().exec("cmd /c set");
}
else
{
p=Runtime.getRuntime().exec("/bin/sh -c set");
}
BufferedReader br=new BufferedReader(new InputStreamReader(p.getInputStream()));
String line;
while((line=br.readLine())!=null)
{
sb.append(line+"<br>");
}
return sb.toString();
}
private String getDrivers()
{
StringBuffer sb=new StringBuffer("");
File roots[]=File.listRoots();
for(int i=0;i<roots.length;i++)
{
sb.append(roots[i]+" ");
}
return sb.toString();
}
