All I am doing is :

 

JasperManager.compileReport("FontsReport.xml");

 

Why?

Hi,

 

Make sure that the DTD files found in the

package "dori/jasper/dtds" are available

in the classpath when you compile your report.

 

If the engine does not find the DTD file through

the classpath, it throws this error.

 

Good luck!

Teodor
