Run Domino Java Web Agent with JfreeChart on Iseries

HCL Domino Domino Forum
1

My Java Agent is on Domino R8.5.2 at Iseries V6R1 , import jcommon-1.0.16.jar and jfreechart-1.0.13.jar.

I could run JfreeChart Java Agent on Notes Client or Domino Designer, it will show me Pie Chart or Bar chart and ChartUtilities.saveChartAsJPEG to local drive c:. Please Refer Code 1.

I got some problems

  1. Can not run this java agent on web, it will show me in the Log

  1. If I replaced (“c:/JFreeBarChart.jpg”) to (“/WMtemp/JFreeBarChart.jpg”), then I run this code with Domino Designer. It can not save Chart to Iseries(AS400 V6R1), it will catch exception “Problem occurred creating chart “ to Java Console.

Have Anyone idea to fix it ?

Thanks in advance.
