Hi,
The java engine uses only .pfb fonts for PDF reports. It might be possible that the font mentioned in the java error message ('cour.pfb') doesn't exist in the directory indicated. Did you check?
Otherwise, are there other 'cour.*' fonts in that directory (/usr/lib/X11/fonts/Type1)? I especially think about a font called 'cour.pfa'. If yes, you can use the Linux/Unix tool 'pfa2pfb' to convert the font (the tool might not be installed by default, so you have to install it).
But other conversion tools exist, for example the 't1binary' tool, part of the 't1utils' package, available for several Linux distributions.
Hope this helps
Best regards,
Romain W.
