Need to capture image coordinates displayed in a browser window

[Ravi Kiran Va]

Hi ,

I am displaying our spatial data in form of a Map (As a Image ) on to the browser window as shown below .

 <input type="image" border="0" SRC="<%=url%>" name="userClick" width="<%=w%>" height="<%=h%>" >

Now i must digitize this , means drawing lines on to the image .

I am able to capture the left click and right clicks of a mouse .

Upon left click i am able to capture coordinates x and y and store them in a session like this .

int x  = request.getParameter("userClick.x)
int y =  request.getParameter("userClick.y);

Upon right click i am getting this values as null please help me how can i get these values .so that i can draw a line

int x  = request.getParameter("userClick.x)
int y =  request.getParameter("userClick.y);

Please help .
