Hi,

Is there a way to read, files present in a folder iteratively in a particular logic using any predefined classes in java api.

Thanks in advance

thank you very much

we have been assigned a project in which files on a remote unix os is to be used like a database for a jsp front end application.Are there any packages or classes in java which would enable easy access of the file, and to extract and insert data effectively into the unix files from the jsp front end application.

1'm sorry, i didn't communicate effectively.

This is the code i wrote.(it works properly for server to one client communication)
public class server
{
Socket s;
JFrame fr;
JTextArea ta;
JTextArea tb;
JButton b;
JPanel p;
BufferedReader br;
PrintWriter pw;
ServerSocket ss;
server()
{

fr=new JFrame("Client Window");
p=new JPanel();
b=new JButton("Send Data");
ta=new JTextArea(3,50);
tb=new JTextArea(30,50);
b.addActionListener(new sending());
p.add(ta);
p.add(b);
p.add(tb);
(fr.getContentPane()).add(p);
fr.setSize(400,300);
fr.setVisible(true);
}




public static void main(String a[])throws Exception
{
server x=new server();
x.makeCon();
x.createProcess();
Thread.currentThread().sleep(500);
}

void createProcess()
{
Thread t=new Thread(new clientread());
t.start();
}


void makeCon()
{
try
{
ss=new ServerSocket(3500);
s=ss.accept();
br=new BufferedReader(new InputStreamReader(s.getInputStream()));
pw=new PrintWriter(s.getOutputStream());
System.out.println("Connection Established With client");
}
catch(Exception e)
{
}

}

class sending implements ActionListener
{
public void actionPerformed(ActionEvent ae)
{
try
{
pw.println(ta.getText());
pw.flush();
ta.setText("");
ta.requestFocus();
}
catch(Exception e)
{
}

}
}



class clientread implements Runnable
{
public void run()
{
String s;
try
{

while((s=br.readLine())!=null)
{
tb.append(s+"\n");
}

}
catch(Exception e)
{
}

}

}



}
