problem when when writing the graph as PNG

Post by snageshbabu » Thu Jan 31, 2008 10:16 am

Hi,
I have a problem when i am calling a servlet from jsp through img tag.
The code is working fine when tested in local, but getting problem when i deployed on DEV.
This is the code in servlet..
OutputStream out = response.getOutputStream();
response.setContentType("image/png");
ChartUtilities.writeChartAsPNG(out, chart, 400, 300);
out.close();

This is the error...

Sorry for the delay responding.

These sound like questions for the regular JFreeChart forum, rather than Eastwood. However, two things to check:

(1) Is your server running in "headless" mode? This is a common issue when something works on your local machine, but doesn't work on the server. The exception messages are not always that helpful. See item 10 in the JFreeChart FAQ for more info:

http://www.jfree.org/jfreechart/faq.html#FAQ10

(2) Are you using JFreeChart 1.0.9 and sending JPEG images back to the client? There is a bug in JFreeChart 1.0.9 (only) with respect to JPEG images (only). You can workaround this by downgrading to JFreeChart 1.0.8 or using PNG images rather than JPEG.

If it isn't either of those things, then I'm not sure.

i need clarification

Post by senthil » Wed Apr 30, 2008 3:56 pm

i have single suggestion :

David all the time when we are asking some issues while using jfrreechart
in jsp

you are saying that it should run in headless mode

but my question is

how it works fine at one time without headless mode in a server setting .how?

I am very eager to know when we can simulate this bug .....

i have already raised in genral forum , please response me ASP

Well, the ClientAbortException sends a clear message.

Your browser did not wait for the image to be sent completely. Maybe the user moved on to a different page, maybe the connection got dropped, whatever it was: You cannot do anything about it and headless mode has nothing to do with it.

HTTP is a network protocol, so you encounter connection errors from time to time. This particular exception is nothing you should worry about, it just tells you that the client went away. Ignore it.
