Package net.sf.jasperreports.engine

Class JasperExportManager

java.lang.Object

net.sf.jasperreports.engine.JasperExportManager

public final class JasperExportManager
extends Object

Facade class for exporting generated reports into more popular formats such as PDF, HTML and XML.

This class contains convenience methods for exporting to only these 3 formats. These methods can process data that comes from different sources and goes to different destinations (files, input and output streams, etc.).

For exporting to XLS and CSV format or for using special exporter parameters, the specific exporter class should be used directly.
