Could not initialize class net.sf.jasperreports.engine.util.JRStyledTextParser

Question

I\'m trying to display my reports on the browser , but I keep getting this error:

Answer 1

This can as well be caused by missing/inaccessible Java 'temp' directory. In Font.java, temp files are being created:

Files.createTempFile("+~JF", ".tmp").toFile();

On one system, the 'temp' dir was missing under Tomcat folder but Java was configured to use it:

-Djava.io.tmpdir=C:\Program Files (x86)\Apache Software Foundation\Tomcat 7.0\temp

BTW. first time around, after restarting Tomcat, the service was actually throwing an IOException, but then JasperReports cached something and on subsequent calls the stack trace was exactly as reported here.
