JRFontNotFoundException: Font '' is not available to the JVM. Please help!!

[saman0suke]

I recently upgraded from iReport 3.0.0 to iReport 3.7.6, I had to changed the iText.jar and jasperreports.jar to the latest version (3.7.6) to make it work, but the oldest reports are giving me this error:

net.sf.jasperreports.engine.util.JRFontNotFoundException: Font '' is not available to the JVM. See the Javadoc for more details.

Most of the new reports works with no problem except for the old ones.......I changed the parameter:

net.sf.jasperreports.awt.ignore.missing.font

true

But I still receive the same error, I don't want to go back to old iReport and jasperreport version, is there anything else I need to do? thanks in advanced, have a nice day!

 UPDATE: I just managed to make it work, however, the solution is too complex, I checked the XML of the report and found this:

<font fontName="" size="10" isBold="true" pdfFontName="Helvetica-Bold"/>

I'm assuming that jasperreports.jar (version 3.0.0) was reading the pdfFontName value, which is deprecated now on the latest version, and that's why I get the error, because it finds nothing on the fontName tag, so i did this with all the empty tags:

<font fontName="SansSerif" size="10" isBold="true" pdfFontName="Helvetica-Bold"/>

and it worked!! but I cannot doing it manually since I have more than 10 reports, is there anything I can do to correct this? thanks!!!

Did you recompile the reports with the newer version of iReports? I ran into this issue when we upgraded from 1.3.3 to 3.7.4.
