NullPointerException when exporting to PDF...

2003-08-04 04:50

Hello. I am repeatedly running into the following NullPointerException whenever I make a call to any of JasperExportManager's exportReportToPdf methods. The following stack trace is generated by the following code:

 

byte[] filebytes = JasperExportManager.exportReportToPdf( jp );

 

However, this stack trace is identical, no matter which exportReportToPdf/PdfFile method is used:

 

java.lang.NullPointerException

Any ideas as to what is going on here?
