I made a servlet that runs and renders a BIRT report, using ReportEngine API.
The only problem is that SVG images (charts) are not shown in Internet Explorer 8 or 7. While running the official BirtViewer webapp they are shown under IE8 too. I peeked into BirtViewer resulting HTML and noticed this meta tag:
<!-- Mimics Internet Explorer 7, it just works on IE8. -->
<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7">
So I tried adding it by hand in my own resulting HTML, but with no changes. I also tried adding it through the servlet (which is the regular way) writing:
response.setHeader("X-UA-Compatible", "IE=EmulateIE7");
immediately after the setContentType instruction, but it not even outputted the meta tag...
EDIT: here is resulting HTML from BirtViewer official webapp (I cleaned up the parts with no interest here):
