Could you post the stacktrace here?

Apparently the code block is ok.

Code:

Okay, now I see the problem was created by the OUTPUT_FILE_NAME parameter. :)

You have 2 possibilities, when exporting a report:

1. Use the OUTPUT_FILE export parameter, and set a java.io.File as parameter value:

exporter.setParameter(JRExporterParameter.OUTPUT_FILE, new File("U:/Repository/presentationBuilder.pdf"));

2. Use the OUTPUT_FILE_NAME export parameter, and set a String representing the file name as parameter value:

exporter.setParameter(JRExporterParameter.OUTPUT_FILE_NAME,"U:/Repository/presentationBuilder.pdf");

In your sample you set the OUTPUT_FILE_NAME parameter with a File value, and this doesn't work.

Regards,
sanda
