<%@ page import="org.apache.poi.hssf.usermodel.HSSFSheet"%>
<%@ page import="org.apache.poi.hssf.usermodel.HSSFWorkbook"%>
<%@ page import="org.apache.poi.hssf.usermodel.HSSFRow"%>
<%@ page import="org.apache.poi.hssf.usermodel.HSSFCell"%>
<%@ page import="java.io.*" %>
<%@ page import="java.util.*" %>
<%@ page import="java.sql.*" %>
<%@ page import="javax.swing.JFileChooser" %>
<%@ page import="java.awt.Desktop"%>
<%@ page isErrorPage='true' %>

    java.util.Date date = new java.util.Date();

    JFileChooser chooseFile=new JFileChooser();

    chooseFile.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
    chooseFile.setDialogTitle("Select a Directory");

    chooseFile.showDialog(null,"Click Me to Save the Folder");
    //String filename = "/tmp/Excel "+System.currentTimeMillis() +".xls" ;




try
