PdfGlyphRenderer exception

[sskotnicky]

Anytime I try to export a report to PDF I get this exception.

Could not initialize class net.sf.jasperreports.engine.export.PdfGlyphRenderer

Any idea, what is causing this and how to fix this?

Btw: I've tried JasperExportManager.exportReportToPdfFile, JasperExportManager.exportReportToPdfStream methods and also creating a JRPdfExporter settings input and output and then calling the exportReport method. I get the same exception all the time.

I have never seen this error before, could you post more exception text? Have you tried to add -Djava.awt.headless=true to your JAVA_OPTS?

Are you using JasperReports IO as you've tagged your question or are you actually writing your own program using JasperReports library. If the later, check that you haven't specified itext dependency beside the one jasperreports comes bundled with.

Thank you very much for the reply.
I am writing a method that gets the JasperReport and exports it to HTML / PDF, because the preview generated has some problems with the arabic font . Export to PDF throws this exception and export to HTML work almost OK. It generates the HTML correctly, but when I print it (or export to PDF), co covers only (around) 80% of page. (I can give you more details if you want).
