Troubleshooting

This error is normally associated with a JVM not being started on a Linux machine in AWT headless mode. JasperReports Server doesn’t provide a virtual X frame buffer on Linux. To prevent Java from trying to connect to an X-Server for image processing in JRS, please modify your application server's startup script to include the following JAVA_OPTS 

-Djava.awt.headless=true

make sure to restart the server after this modification before testing the report again.

The other possible causes of this error re:

  • one or more jar files are missing from Jasperreports Server installation for some reason

  • one or more default system fonts are not accessible in this environment

I'd start by checking if all jars are present in the <js-webapp>/WEB-INF/libs folder by comparing the contents of it with the same folder in a working environment.

If that doesn't help, here is a stackoverflow.com thread where people were having the same error and provide a couple of solutions that worked:
