Just a thought... Try calling .jrxml file instead .jasper

[khare.siddharth28]

have you compiled your jrxml file into jasper object.
secondly why are u using this implementation of JasperRunManager.runReportToPdf when your Connection object is null, instead use a JREmptyDataSource.(possibly JasperEngine is trying to use Connection object to open a connection and getting a null pointer exception)
