Getting java.awt.HeadlessException when running the JasperViewer.viewReport (JasperPrint) method

Question

I get an error with this code running on Ubuntu 11:

JasperReport jasperReport = JasperCompileManager.compileReport("/resources/etiquetas/etiquetaEndereco.jrxml"); JasperPrint print = JasperFillManager.fillReport(jasperReport, parametros); JasperViewer.viewReport(print);

As the Java documentation shows, java.awt.HeadlessException :

Throw when a code dependent on a keyboard, display, or mouse is called in an environment that does not support a keyboard, display, or mouse.

and for java.awt.GraphicsEnvironment :

The GraphicsEnvironment class describes the collection of GraphicsDevice and Font objects available for a Java (tm) platform-specific application.

Make sure your source report file ( etiquetaEndereco.jrxml ) calls fonts that cannot be installed on your system.
