Hi Friend,

Try the following code:

import java.sql.*;
import java.awt.*;
import java.io.*;
import javax.swing.*;
import java.awt.image.*;
import java.awt.event.*;
import javax.imageio.ImageIO;

public class InsertImage {
static JTextField text=new JTextField(20);
static JButton button=new JButton("Save");
static JPanel panel=new JPanel();

public static void main(String[] args) {
JFileChooser chooser = new JFileChooser();
int returnVal = chooser.showOpenDialog(null);
final File file ;
if(returnVal == JFileChooser.APPROVE_OPTION) {
file = chooser.getSelectedFile();
final String name=file.getName();
System.out.println(name);
text.setText(name);
panel.add(text);
panel.add(button);
button.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e){
try{
Connection con = null;
String url = "jdbc:mysql://localhost:3306/";;
String db = "test";
String driver = "com.mysql.jdbc.Driver";
String user = "root";
String pass = "root";
FileInputStream fis;
Class.forName(driver);
con = DriverManager.getConnection(url+db, user, pass);
PreparedStatement st = con.prepareStatement("insert into file(file_name,file_data) values(?,?)");
fis = new FileInputStream(file);
st.setString(1,name);
st.setBinaryStream(2, (InputStream)fis, (int)(file.length()));
int s = st.executeUpdate();
JOptionPane.showMessageDialog(null,"image is successfully inserted.");
}
catch(Exception ex){}
}
});
JFrame f=new JFrame("Insert Image");
f.add(panel);
f.setVisible(true);
f.setSize(300,100);
}
}
}

Thanks
