Subreport and java design

2003-08-19 06:18

Hi!

 

I need help with sub-reports and java programming design (I?m not programming a XML file).

 

How can I set the JRDesignSubreport object to accept a custom DataSource?

 

I did it in with de XML design, but I need it in Java.

 

I?m using JasperReports 0.5.0.

 

Thanks!

How about trying to pass the object you want to iterate through in the subreport to by way of a subreport parameter?

This way?

 

JRDesignBand band = new JRDesignBand();

 

JRDesignSubreport subreport = new JRDesignSubreport();

 

expression = new JRDesignExpression();

expression.setValueClass(CityDataSource.class);

subreport.setDataSourceExpression(expression);

band.addElement(subreport);

 

jasperDesign.setDetail(band);

Hi,

 

You have not set the text content of your

data source expression using expression.setText().

Take a look at the "noxmldesign" sample.

It will give you some hints.

 

I hope this helps.
