Because I don't see any iframe tags in sources, but I read in the Birt online help:
{quote}
1. HTML tab
When you click on this tab. It will show the complete report in an iframe.
2. PDF tab
When you click on this tab. It will render the report in a pdf format

> Hello all,
> I have created a patch to solve a viewer servlet problem and uncomment the viewer servlet in the birt webapp. To do this will allow a user to use BIRT Web Viewer to render a report by coping a webcontent directory from birt-runtime-x_x_x/WebViewerExample directory and paste into the birt webapp directory ($OFBIZ_HOME/specialpurpose/example/webapp/birt).
> These are URLs to render example reports using BIRT Web Viewer.
