Retrieving a chart object from a report and exporting to PNG

Uffe Ronne

Hello,

I'm currently developing a web application in JBoss AS 6.1. I want to be able to display data in a chart based on data from an Oracle database. I have created a report using the report designer containing a single chart and I have been able to render this to HTML and PDF using the 3.7.1 runtime environment. However my original plan was to render it to PNG and embed it on one of my web pages. But I can't seem to find a way to do this. Is this possible and does anyone have a code sample?

Best regards

Uffe

You could use the chart engine api in servlet, but then it would not use the datasource from the report. The report uses an img src=.. tag to show the chart. Are you trying to get the image data or if the img src is ok why not use the birt tag libraries in your app and then embed the report (or the chart using a bookmark) in your web page?

Hi Jason 
 
Ahh why didn't I think of that. Tag libs are the way to go I think. I will investigate :-)
