I think many people got the same problem and too hard to find the way to solve it.
I deployed Jasper Report Server on Glassfish 3.0, JRS works normally. My server is CentOS 5, and Microsoft True Type fonts are installed in /usr/share/fonts/msttcorefonts/ folder. All ttf files are copied to JAVA_HOME/jre/lib/fonts folder too.
I used iReport 4.7.0 to export the font extension jar files and copy them to WEB-INF/lib in JRS application's folder in Glassfish.
The report are showing in browser OK, but when export to PDF, Unicode characters are missed. In Jasper Report XML (JRXML) I double check "PDF Embedded" propertie is checked.
I also tried to add font extension jar files into repository and link resource to Jasper Report. But the PDF export still missed unicode characters.
I really don't know how to solve this problem.
Please help me. Thanks in advanced!
