问题
I need to generate charts using JFreeChart and then export them to PDF using Apache PDFBOX. I don't want to use iText as it cannot be used in proprietary software.
I searched all over Google, but no luck! Has anyone done it?
回答1:
Copy the OutputStream from your chosen writeChartAs*() method in ChartUtilities to the InputStream used to create a PDXObjectImage in AddImageToPDF. A typical copyStream() implementation is shown here.
Addendum: Alternatively, use piped streams to copy from output to input, as shown here and here.

You can try using JasperReports. They are a bit heavy, but working good.
