You been asked by number of our members to also include any relevant coding. This is missing and without it there is little hope somebody will attempt to help you...

<%
BufferedImage image = (BufferedImage)session.getAttribute("image");
String path = application.getRealPath("/");
String imagePath = path+"images//mapimage.jpeg";
File file =new File(imagePath);
ImageIO.write(image,"jpeg",file);
%>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">

<script type="text/javascript">

var image1;
var x1;
var y1; 
var isDragging=false;
var dx;
var dy;
var x2;
var y2;
var x;
var y;
var ob;

window.onload = init;
document.onmousemove = mM;
document.onmouseup = mU;

function init() 
{
	ob = document.getElementById("image1");	
}

function mD(ob,e) //on mouse down event
{
	image1 = ob;
	
	if (window.event) e=window.event;	
	
	x1 = e.clientX;
	y1 = e.clientY;
	isDragging = true;
	
	return false;
}

function mM(e) //mouse move
{
	if (!isDragging) return;
	
	if (window.event) e=window.event;
	x2 = e.clientX;
	y2 = e.clientY;
	
	
	return false;
}

function mU() //mouse up

	if (!isDragging) return;
	
	isDragging = false;
	dx = x1-x2;
	dy = y1-y2;
	document.displayMapForm.dx.value = dx;
    document.displayMapForm.dy.value = dy;
        
    if(isNaN(dx) && isNaN(dy))
    {
    	return false;
    }   
	else
	{						
 		document.displayMapForm.submit();
 	}	
}

function move()//displays coordinates as mouse moves on image
{
	window.status = " X = " + event.x + " Y = " + event.y 
}

the same code was working fine in ie6.

Member Avatar for kvprajapati

With little modification now, your code is working.

BufferedImage image = (BufferedImage)session.getAttribute("image");
   String path = application.getRealPath("/");
   String imagePath = path+"images//mapimage.jpeg";
   File file =new File(imagePath);
   FileOutputStream fos=new FileOutputStream(file);
   ImageIO.write(image,"jpg",fos);
   fos.flush();
   fos.close();

If you don't get an answer soon don't start another thread asking the same thing. What did you expect? That the very first minute you posted everyone should give you the solution? Your impatience was very annoying, flooding the forum with new threads.
We are not here to serve your needs nor we are obligated to give you immediately the answer.
If you didn't get a reply then wait for someone who knows the answer to post. Posting and posting again will not change things.
