You don't fill an XML file. You complie the XML file into the .jasper file. Then you can fill the .jasper file.

Ok.

I having the same problem.

The difference is that I'm filling the .jasper file...

look:

 

line 27 JRResultSetDataSource jrRS = new JRResultSetDataSource( rs );

line 28 Map parameters = new HashMap();

line 29 JasperFillManager.fillReportToFile("c:/backup/dug/ireport/relas/bairros.jasper", parameters, jrRS);

line 30 JasperRunManager.runReportToHtmlFile("c:/backup/dug/ireport/relas/bairros.jasper", parameters, jrRS);

line 31 JasperViewer.viewReport( "c:/backup/dug/ireport/relas/bairros.html", false );

 

The file .html (or .pdf) is created but not shown...

Instead I got the exception:

 

java.io.StreamCorruptedException: invalid stream header
