Error at the time of viewing reports.

NikhilNaik

hi all,

we have integrated BIRT in an application.
But when viewing reports it is giving error
"org.eclipse.birt.report.service.api.ReportServiceException: Report document instance is empty. ".

Does any one know the reason for the same?

Please help me in solving this...

The Exception Stack Trace for the error are as given below

Hi All

I am getting the above error while trying to view the same report again...and again.

Is there any limitation on opening a single report?

Thanks

One reason of getting this error is try to generate the same report more than once.

Like say you are generating the report on click of button. Before repoorts get loaded button is clicked again. In that case the first report will get this error.

Is there any scenario like this.

Reason is BIRT overwrites the report same report for the same session.

Hi all,

I'm facing the same issue with 2.2.1 and 2.2.2 releases : after about 10 refresh of the same report, I get the the error message "Report document instance is empty" and the same stack trace.

My environment below :
- AIX 5.3 (PowerPC 570)
- java version "1.4.2"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2)
Classic VM (build 1.4.2, J2RE 1.4.2 IBM AIX build ca142ifx-20061116 (142SR6 + 111682 + 111872 + 110979) (JIT enabled: jitc))
- IBM WebSphere Application Server - ND, 6.0.2.17
Generation number : cf170648.10

It works fine on a Windows environment.
Does anyone have news about this issue? Does anyone test the latest release (2.3)?
