Because of using JasperReports 7 you need to take into consideration the following breaking changes:
-
breaking backward compatibility of serialized/compiled *.jasper report template files,
mostly because of historical deprecated serialization code removal/cleanup mentioned above
(source *.jrxml report templates need to be recompiled to *.jasper using the new version of
the library); -
breaking backward compatibility of source *.jrxml report template files and *.jrtx style
template files by replacing the Apache Commons Digester based parsers with Jackson XML object
serialization. *.jrxml and *.jrtx files created with version 6 or older can no longer be loaded
with version 7 or newer of the library alone. The conversion from the old file formats to the new
file formats and back can be made using Jaspersoft Studio 7 and later versions of it;
