It looks like the .jsp is adding 5 new line characters at the start of the image file because of the imports, if I remove these new line characters, the image opens everywhere fine. I'm going to put the code from the jsp in a class to avoid this.
It looks like a bug in FusionChartsSave.jsp, because the data is being sent in the request, but the created image file can't be opened in browsers or ms image viewer.
I have same problem. The image is corrupt after saving.
I'm using java 1.4.2 weblogic 8 and the downloaded script FusionChartsSave.jsp from the latest version.
