Solución:




Esto se puede estar dando por falta de la librería poi.jar en la carptea lib del web-inf  o  como en mi caso se dio porque reemplace el archivo PDFReport.ini de windows a un linux.

En el archivo que esta en el SO windows contiene una linea para la fuente predeterminada:

Microsoft Sans Serif= c:\windows\fonts\micross.ttf

Ejemplo en linux la crea asi:

Microsoft Sans Serif= /usr/java/jdk1.6.0_21/jre/lib/fonts/LucidaSansRegular.ttf

O simplemente borra ese archivo (PDFReport.ini)
