JasperReports 4.6.0 released

[Teodor Danciu]

 
JasperReports Library 4.6.0 Change Log
==========================================
 
- improved JasperReports configuration infrastructure by the introduction of a JasperReportsContext, 
an new interface from where JR configuration properties are read and JR extensions are loaded.
This allows different configurations of the JR engine to exist simultaneously in the same JVM;
 
- improved JasperReports Web Framework which now features a centralized controller to dispatch
actions triggered by end user interactions in the report viewer. Actions are backed by atomized 
commands that modify the report metadata on-the-fly, with support for undo/redo operations, 
to reflect changes in the report output;
 
- introduction of reusable Web report viewer APIs, featuring configurable report viewing servlets,
and built-in Javascript modules that can be used to create custom interactive report viewers in Web
applications embedding the JasperReports Library.
This is demonstrated in the new /demo/samples/webapp-repo sample where two different looking versions
of the same build-in JR interactive report viewer are used to displays interactive reports;
 
- enhanced interactivity in the table component, with support for column formatting, hiding, resizing,
moving, sorting and filtering, all leveraging the new action-based JR Web Framework controller and its 
interactivity supporting report viewer Javascript APIs;
 
- introduction of a data caching API that helps avoid re-querying the report's data source, 
for performance reasons, while interactively viewing the report using an interactive report viewer
created based on the new JR Web Framework;
 
- added new page related events in the asynchronous report filler to support asynchronous page display
in interactive report viewers;
 
- added support for message providers that can be plugged into JR as extensions, to allow 
internationalization of interactive custom components UIs;
 
- minor bug fixes and improvements;
