Another very important issue is that the default report viewer that comes with the library does not know

how to deal with document hyperlinks that point to external resources. It only deals with local

references and can redirect the viewer to corresponding local anchor.

However, JasperReports offers you the possibility to handle yourself the clicks made on document

hyperlinks that point to external documents and not local anchors.

The only thing you have to do in order to achieve this, is to implement the

dori.jasper.view.JRHyperlinkListener intece and to add to register with the viewer

component an instance of this listener class, using the addHyperlinkListener() method exposed

by the dori.jasper.view.JRViewer class.

By doing this, you make sure the viewer will also call your implementation of the gotoHyperlink()

method in which you handle yourself the external references.

10.4 Exporting to New Output Formats

The JasperReports library continually evolves and improves. Among the features that are likely to be

introduced with time is the ability to export to new documents formats, besides PDF, HTML and XML.

In order to extend diversify in this direction, without affecting the existing functionality, JasperReports
