Not able to view BIRT reports on Unix

[NikhilNaik]

Hi,

We have integrated BIRT in an application.

The reports are working fine on Windows env., but when I tried to run reports on UNIX env. I get the ERROR

"org.eclipse.birt.report.service.api.ReportSer vice Exception: Report document instance is empty. "


Can you please help me in solving this...
