How to use the JasperReport to export csv

2002-12-09 10:22

Hello,

I tried to export the PDF and CSV at the same time:

After the compile, I can use: JasperExportManager.exportReportToPdfFile and JasperExportManager.exportReportToHtmlFile

to get the PDF and HTML files. I can't find:

JasperExportManager.exportReportToCsvFile

So I tried to use the JRCsvExporter.exportReport() to get the CSV file, but don't know which parameter to set up and what value I should set the INPUT_FILE. Thank you for help in advance.

Best Regards,

Jessica

Hi,

 

I agree that the exporter parameters are not yet

well explained.

You have to supply as INPUT_FILE the .jrprint file

produced by the report filling process.

Or you can directly supply a JasperPrint object

using the JASPER_PRINT parameter.

 

The result of the export process is specified using

the OUTPUT_FILE or OUTPUT_STREAM parameters.

 

The best way to understand exporters is to look

inside their exportReport() method.

This is an open source project.

:)

 

I hope this helps.

Teodor
