I have an action where I create graph(s), and I need to display them
in the page. It is ArrayList<JFreeChart> that I need to show, but for
the start I will try to display only one graph.
Action code goes like this:
public class ChartDisplayAction () {
...
execute() {
HttpSession session = servletRequest.getSession();
JFreeChart mygraph = ...creating graph...
BufferedImage myBuffered = mygraph.createBufferedImage(600, 400);
session.setAttribute("myBuffered", myBuffered);
}
...
}
.jsp page code:
<img src="<%=session.getAttribute("myBuffered")%>" border=0 usemap="#imageMap">
Obviously, I am making the mistake here (most probably when I am
trying to put myBuffered in session scope), but chart that I want to
display is not in file, it is in a stream, and there must be a way to
pass the stream to .jsp page. How do I do that?
Thanks!
