Error at the time of viewing reports on UNIX.

NikhilNaik

hi all,

we have integrated BIRT in an application.

The reports are working fine on Windows environment, but when i try to view reports on Unix environment I am getting this error.

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

Does any one know the reason for the same?

Please help me in solving this...

NikhilNaik:
Do you have the classpath set up?
What is your unix environment like ?
How are you deploying and running the reports?
Are you able to run any other report in this environment(without charts)?
Do you have necessary GDI library installed on your Unix Box?

I am able to view reports quite some times.
But it is giving this error randomly.
I am able to view reports near about 5 times after restarting the server.
But when I tried to view report after viewing near about 5 reports, I am getting this error.

Even I am able to view report having charts(But thats only when I run the report at the 1st or 2nd time)

And after getting this error no any report is working.

Please Reply ASAP.
