Couldn't find 3-letter language code for en_en---- Error code:-2147467259

Hi team,

While i am trying to export the reportclient document to PDF , i am facing problem.

I am using crystal reports 2008.

Java code used to export to PDF :

ByteArrayInputStream byteInputStream = (ByteArrayInputStream) reportClientDocument.getPrintOutputController().export(ReportExportFormat.PDF);

Error shown up in logs due to the above line

com.crystaldecisions.sdk.occa.report.lib.ReportSDKException: Couldn't find 3-letter language code for en_en---- Error code:-2147467259 Error code name:failed

at com.crystaldecisions.sdk.occa.report.application.PrintOutputController.if(SourceFile:237)

at com.crystaldecisions.sdk.occa.report.application.PrintOutputController.export(SourceFile:147)

at com.crystaldecisions.sdk.occa.report.application.PrintOutputController.export(SourceFile:128)

Need help to find the root cause of this issue and the appropriate fix.

Thanks
