NullPointerException PdfDocument.close

2005-06-09 08:27

I generate a PDF document within a servlet.

I get the following exception :

 

ExceptionConverter: java.lang.NullPointerException

at com.lowagie.text.pdf.PdfDocument.close(Unknown Source)

at com.lowagie.text.Document.close(Unknown Source)

at net.sf.jasperreports.engine.export.

JRPdfExporter.exportReportToStream(JRPdfExporter.java:416)

at net.sf.jasperreports.engine.export.

JRPdfExporter.exportReport(JRPdfExporter.java:241)

at net.sf.jasperreports.engine.

JasperExportManager.exportReportToPdf(JasperExportManager.java:188)

 

It only occurs on Websphere 5.1 on windows XP. I never had a single problem in

the WSAD environment.

 

I use jasperreports-0.6.8.jar and itext-1.3.jar but i have the same thing with

the 0.6.6 version of jasperreport and any other version of itext (1.01).

 

Notice :

- i have no security manager restriction about 'getCLassLoader' on the

application server.

- i have tried to generate a pdf file before sending the response to the browser

but the same thing happened.

 

Thanks for any kind of help.

Problem solved.

It comes from an old library version of itext (0.9) which was in the application server classapth.
