[Amaresh]

If anyone is having program on it, or if anyone is having some or the other details on it, then please provide me solution for it. Thank you in advance.

Hello, I have a code which can help you if you are using the servlet for displaying the image. So, make use of it.

protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException 
{ 
HttpSession HSession = req.getSession();
ServletContext Servletcon = getServletContext();
String str = Servletcon.getRealPath("1-30.jpg"); 
String mtype = Servletcon.getMimeType(str); 
if (mtype == null) 
{ 
Servletcon.log("Could not get MIME type of"+ str);
resp.setStatus(HttpServletResponse.SC_INTERNAL_SERVER_ERROR); 
return; 
} 
File file = new File(str);
resp.setContentLength((int)file.length()); 
FileInputStream in = new FileInputStream(file); 
resp.setContentType("image / jpeg" );
BufferedInputStream out2 = new BufferedInputStream(resp.getOutputStream()); 
byte by[] = new byte[ 32768 ]; 
int index = in.read( BY, 0, 32768 ); 
while ( index! = -1 ) 
{ 
out2.write( BY, 0, Index );
index = in.read( BY, 0, 32768 ); 
} 
out2.flush(); 
}

Hello, I think you can achieve this with the tow steps as below:
1 - to send an image on the server and register it there you need rights or read and write. If you are making a distributed application then it is quiet complicated. So you need to move to an archiving db saved byte.
2 - You can simply do one thing, in your jsp you can call a link redirecting to a servlet through the web.xml treatment after interrogations that will send the database table in byte with the associated mime types.

If you are making use of the swing or awt then you can simply perform it with the help of code below:

Public void paintComponent(Graphics g)
{
ImageIcon icon = new ImageIcon("myimage.jpg ");
Image image = icon.getImage();
g.drawImage(picture,0,0,null);
}

Hey, I have got one code for the displaying image on the page. Make use of it. It is so simple to understand.

import javax.swing .*;
import java.awt .*;
Testing class extends JFrame
{
Testing ()
{
SetTitle ( "Image");
setSize (800, 500);
pan = new Panel ();
getContentPane (). add (pan);
}
private JPanel panel;
}
class Panel extends JPanel
{
Public Panel ()
{
Photo = getToolkit (). GetImage ( "photo.jpeg");
}
public void paintComponent (Graphics g)
{
Super.paintComponent (g);
int x = 10, y = 10;
if (photo! = null)
{
g.drawImage (image, x, y, this); System.out.println ( "photo");
}
}
private Image image = null;
}
public class TestMenu
{
Public static void main (String args [])
Testing (fen = new Testing ();
fen.setVisible (true);
}
}

This is so simple in java. You just need to make use of the two lines of code below in your program. Just make use of them and solve your problem.

ImageIcon icon = new ImageIcon(picture);
image = icon.getImage();
