Hi Someliang, We had a similar issue with this icon showing - if you've not been able to fix it since, it's caused by jasper using the java graphics library, which tries to start a windows session to do it's rendering. This can be fixed in any java application by specifying java.awt.headless=false in the jvm properties. See here for details: http://www.oracle.com/technetwork/articles/javase/headless-136834.html

I beleive that the base64 string needs to be enclosed in double quotes so that ireport doesn't try to process it. eg. <!CDATA["iVBORw0KGg....etc"]].[/code]Hope that helps.

In regards to this; I've been having trouble with adding multiple images encoded as base64, and have managed to work out that all image data must be loaded first before any reading is done, otherwise ireport simply shows a blank image. I've acheived this by ordering the jrxml to have all base64 data before any variable operations to load the data from it. It seems quite straightforward now i think of it, but it may help someone hopefully.
