Solution; this came down to accidently using the java string escape character in the windows path specified for SAVEPATH. It is however a problem that occurs only when using JRockit

I have narrowed down the problem. It only happens using the Oracle JRockit JVM, which is in use on all our WebLogic instances. Switching my development machine to use the standard edition JVM and all export/save options work as expected.

Hi, I have a Java app deployed on WebLogic 11g (10.3.5) using FusionCharts 3.2.1. I have configured the "Save as x" (PDF/PNG) option, however upon clicking this I get this exception, and my application falls over; ]] Root cause of ServletException. java.lang.NullPointerException at java.io.File.<init>(File.java:222) at com.fusioncharts.exporter.error.ErrorHandler.doesServerSaveFolderExist(ErrorHandler.java:200) at com.fusioncharts.exporter.servlet.FCExporter.init(FCExporter.java:248) at weblogic.servlet.internal.StubSecurityHelper$ServletInitAction.run(StubSecurityHelper.java:283) Following the readme, I have placed fusioncharts_export.properties in WEB_INF/classes and configured the values appropriately. I also have the chart xml with the arrtibute exportAction='download', as I do not want to write the file to disk at all. This same application works without fusioncharts_export.properties at all on JBoss. I am not sure what is causing this problem, so any help you can give would be appreciated.
