Hi,
Unfortunately this doesn't give me much information, what is
BirtReportBinder? I think it if it's working for table reports, it's really
a configuration problem. Can you try to put an image in your report and see
if it works?
Please double check the instructions there
http://www.eclipse.org/birt/deploy/ There is also a sample application
included to show reports in web apps, you might want to try it as well.
Thanks,
David Michonneau

Can you post a new message regarding this issue so that somebody familiar
with the sample app can help you?
