detect "The document has no pages." in java code

[callkalpa]

Is it possible to know whether a JasperPrint is an empty document or not before viewing with a JRViewer?

What I want to do is to check whether the JasperPrint has some data and only if it has some date, display JRViewer and the report.

So please help me.

 

Thanks in advance.

I found a way, although it may not be the best, it works. :-)

Code:

// jp is the JasperReportif(!(jp.getPages().toString().equals("[]"))){    JRViewer jrv = new JRViewer(getJP());    Container c = getContentPane();    c.add(jrv);    setDefaultCloseOperation(DISPOSE_ON_CLOSE);    Main.getMainGUI().getMainPane().add(this);    setClosable(true);    setIconifiable(true);    setTitle(getReportTitle());    setBounds(this.getParent().getBounds());        setVisible(true);}

Hi,

why not:

if (jasperPrint.getPages().size() != 0)
