请教高手:
jsp如何将客户端的txt/Excel文件中的数据一行一行地读取出来？

你好，我试过了你的代码，发现readLine()总是读取第一行，请问如何继续读取下一行呢？
谢谢你!

读Execl文件可使用JDBC方式读取

[pqds]

DataInputStream in = new DataInputStream(new BufferedInputStream(System.in));
try{
String s=in.readLine();
File f = new File(s);
if(!f.isFile())
{
System.out.println("input is not a file!");
this.input();
return;
}
Vector x = new Vector();
int linenum=0;
float InvestAve=0;
BufferedReader inf = new BufferedReader(new FileReader(s));
String c = inf.readLine();
//System.out.println(c);
while(c!=null)
{
System.out.println(c);
}
