Newbie: Please help

2003-10-06 14:42

I am new to JasperReports. With my first Jasper Report I am having trouble printing "detail" section.

 

Your help will be greatly appreciated.

 

Details:

Modeled my first <report>.xml from demo/samples/jasper/FirstJasper.xml

 

I have tried filling the report two separate ways:

//---

JasperFillManager.fillReportToFile(fileName, parameters,getConnection());

JasperFillManager.fillReport(fileName, parameters, new SimpleDataBean());

--//

 

where getConnection() provides connection handle to a JDBC source.

And in second approach: SimpleDataBean is a simple bean which implements JRDataSource

 

Either way my report does not print any details.

Header, title, footer etc. get printed.

 

I can post entire <report>.xml if someone may like.

 

Any pointers will be helpful.

Hi,

 

The detail section is generated once for each record

in the report data source.

If there are no records, the detail never gets generated.

 

Try suplying this as a report data source:

 

new JREmptyDataSource(1)

 

It will create a data source with one record in it.

The number of virtual records is specified by

the parameter in the constructor.

 

I hope this helps.
