Hi Friend,

Actually that code is not related to apache server. The classes we have used belongs to Jakarta api. You need this api in order to create an excel sheet.
We are providing you another code, that will take the database vales from JTable to Excel sheet.

import javax.swing.*;
import java.awt.*;
import java.io.*;
import java.awt.event.*;
import java.sql.*;
import java.util.*;
import javax.swing.table.*;
import org.apache.poi.hssf.usermodel.HSSFSheet;
import org.apache.poi.hssf.usermodel.HSSFWorkbook;
import org.apache.poi.hssf.usermodel.HSSFRow;
import org.apache.poi.hssf.usermodel.HSSFCell;

class Form extends JFrame{
ResultSet rs;
Form(){
String data[][] = {{"",""}};
String col[] = {"Name","Address"};
final DefaultTableModel model = new DefaultTableModel(data,col);
final JTable table = new JTable(model);
JScrollPane pane=new JScrollPane(table);
JButton button=new JButton("Export");
JPanel panel=new JPanel();
JPanel panel1=new JPanel();
JPanel panel2=new JPanel();
final HSSFWorkbook wb = new HSSFWorkbook();
final HSSFSheet sheet = wb.createSheet("Excel Sheet");
try{
Connection con = null;
Class.forName("com.mysql.jdbc.Driver");
con = DriverManager.getConnection("jdbc:mysql://localhost:3306/test";, "root", "root");
Statement st = con.createStatement();
rs= st.executeQuery("Select * from data");
while(rs.next()){
model.insertRow(table.getRowCount(),new Object[]{rs.getString("name"),rs.getString("address")});
}
model.removeRow(0);
panel1.add(pane);
panel2.add(button);
panel.add(panel1);
panel.add(panel2);
add(panel);
button.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent ev){
try{
HSSFRow rowhead = sheet.createRow((short)0);
rowhead.createCell((short) 0).setCellValue("Name");
rowhead.createCell((short) 1).setCellValue("Address");
int index=1;
int count=table.getRowCount();
for(int i=0;i<count;i++){
Object obj1 = GetData(table, i, 0);
Object obj2 = GetData(table, i, 1);

HSSFRow row = sheet.createRow((short)index);
row.createCell((short) 0).setCellValue(obj1.toString());
row.createCell((short) 1).setCellValue(obj2.toString());
index++;
}
FileOutputStream fileOut = new FileOutputStream("c:\\Hello.xls");
wb.write(fileOut);
fileOut.close();
Runtime rt = Runtime.getRuntime();
rt.exec("cmd.exe /C start C:\\Hello.xls");
}
catch(Exception ex){}
}
});
}
catch(Exception e){}
}
public Object GetData(JTable table, int row_index, int col_index){
return table.getModel().getValueAt(row_index, col_index);
}
}
class JTableToExcel{
public static void main(String arg[]) {
try
{
Form frame=new Form();
frame.setSize(450,200);
frame.setVisible(true);
}
catch(Exception e)
{}
}
}

Thanks

Dear Friend, From your code, I am able to complete my project of Exporting the JTable to Excel and also Importing the same Excel to JTable that is two way movement of data which was not happening initially.

Heartily thanks to you..... basugade.pravinkumar@gmail.com b.pravin@infobrainbox.com

Dear Sir, Your Code is Excellent,But in case of exporting data from Oracle DataBase to Excel Seet Some Packages are import like import org.apache.poi.hssf.usermodel.HSSFSheet; import org.apache.poi.hssf.usermodel.HSSFWorkbook; import org.apache.poi.hssf.usermodel.HSSFRow; import org.apache.poi.hssf.usermodel.HSSFCell;

How to import these Packages in Simple java Program and JDevloper IDE.

Thanks For your Help and Support. Amit Kumar
