I have an action in my application that generates a PNG image from
some text stored in a session object. My view is very simple:
<[EMAIL PROTECTED] contentType="image/png"%>
<%
java.io.OutputStream os = response.getOutputStream();
java.awt.image.BufferedImage buffer = (java.awt.image.BufferedImage)
request.getAttribute("imageBuffer");
javax.imageio.ImageIO.write(buffer,"png",os);
os.close();
%>
Thats it. My action loads imageBuffer with the image data.
The first time I load the page I get the error:
"java.lang.IllegalStateException: getOutputStream() has already been
called for this response"
Is there a better way to accomplish what I am after? I would prefer
to load the page one time and have it work, rather than the refresh.
Thanks in advance...
