[birt-report-designer-dev] Error in report

Hello All...

I am Designing a report Which will run on IE 6.0 with code windows-1256 (arabic windows) and birt is using utf-8 code ..When I put My Variabable in url and run:

http://localhost:8080/birt-viewer/run?__report=report\DetailReport.rptdesign&rptNAT=ÚÑÈí

it gives me error:

There are errors on the report page:

+ There are error(s) in Data : 328

with frameset it is ok:

http://localhost:8080/birt-viewer/frameset?__report=report\DetailReport.rptdesign

it asks me parameter , i put ÚÑÈí in it which brings data but i can not print from browser

in print preview it is not as it comes on browser

I am using Oracle Database with Code page 1256 can anyone tell me what is a problem and how can i solve it ...and how can i print report from birt viewer (frameset ) from browser

I am Using OC4J for WebServer can i use it with birt also...??

Thanks ...Raza
