I have deployed BIRT viewer on my local windows PC and after "Processing, Please Wait...." disappears, nothing would be shown on the preview page, only buttons available. I am only able to export the data to CSV (surprisingly). Does this mean my rptdocument is working, but the preview can't be generated?
Occasionally, the below error would appear in the ReportEngine logs after a very long time (15mins?)
org.eclipse.birt.report.engine.api.impl.RunTask doRun SEVERE: There is insufficient memory to execute this report.
I have solved the problem on my local PC by increasing tomcat 7 heap (1gb) and permgen (512mb) size. However, when i deploy to my linux machine (with plenty of RAM), i can't seem to work around this issue regardless of the increase! (tried 10gb for heap and 4gb for permgen)
Here are the specs:
I would like to consult you guys on what steps should I take next to debug my linux instance... Thanks for helping!
