Hi Friend,

Follow these steps:

1. Open Data Sources (Start->Settings->Control Panel->Administrative Tool->Data Sources(ODBC)

2. Open User DSN tab
3. Add a user DSN
4. Select Microsoft Excel Driver(*.xls)
5. Select work book or excel file and Create the DSN name (e.g excel)
6. Click "Ok" and restart your compiler.
7. Compile the following java code:

import java.sql.*;
import java.util.*;
import javax.swing.*;
import java.awt.event.*;
import javax.swing.table.*;

public class JDBCExcel{
public static void main (String args[]){
Vector columnNames = new Vector();
Vector data = new Vector();
JPanel p=new JPanel();
try {
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection conn=DriverManager.getConnection("jdbc:odbc:excel","","");
Statement st=conn.createStatement();
String query="select * from [Excel sheet$]";
ResultSet rs=st.executeQuery(query);
ResultSetMetaData md = rs.getMetaData();
int columns = md.getColumnCount();
for (int i = 1; i <= columns; i++) {
columnNames.addElement( md.getColumnName(i) );
}
while (rs.next()) {
Vector row = new Vector(columns);
for (int i = 1; i <= columns; i++){
row.addElement( rs.getObject(i) );
}
data.addElement( row );
}
rs.close();
st.close();
}
catch(Exception e){
System.out.println(e);
}
JTable table = new JTable(data, columnNames);
TableColumn col;
for (int i = 0; i < table.getColumnCount(); i++) {
col = table.getColumnModel().getColumn(i);
col.setMaxWidth(250);
}
JScrollPane scrollPane = new JScrollPane( table );
p.add( scrollPane );
JFrame f=new JFrame();
f.add(p);
f.setSize(600,400);
f.setVisible(true);
}
}

Note: In the query, [Excel sheet$] is the sheet name of excel file.

Thanks
