You can use HTML gadget to display e.Report in BIRT 360 dashboard.  The HTML gadget uses either a link (URL) to a HTML content OR HTML content itself. To display e.Report you can use either approach, but in each case you will need to format the URL differently.  For example, if an e.Report "sample.roi" is located in folder "/Home/administrator", the HTML content would look like:

   <script>
window.location="http://hostname:8900/iportal/servlet/ViewPage?fromDashboard=true&showBanner=false&name=/Home/administrator/sample.roi&fileType=roi&format=DHTML&page=1&scalingfactor=100";
</script>

 If you choose URL in HTML gadget, then you would need to escape the ampersand, so the URL would look like:

http://hostname:8900/iportal/servlet/ViewPage?fromDashboard=true&showBanner=false&name=/Home/administrator/sample.roi&fileType=roi&format=DHTML&page=1&scalingfactor=100

 In both cases update the "hostname" and "port" information to your specific instance of BIRT iServer.
