Data sources problem...urgent pls help

2003-10-16 22:47

I am generating a report with 2 sub reports. I have to take data into the two subreports using two different data sources. In the <dataSourceExpression> I have mentioned the parameter from which I have to take the Datasource. I am passing it as a Map containing this Parameter Name and the Custom Data sourec object. But when I fill the report, I have to pass a thrid parameter. I don't know what to pass. Here is my statements.

 

Map parameters = new HashMap();

 

parameters.put("ProductsSubreport", subreport);

 

JasperFillManager.fillReportToFile(fileName, parameters, null);

 

What should I pass in place of null???

the third parameter is datasource..which shud not be null...

if it is null then from where ...the data for your tables come...?

even u fill them from other ways..it will not

fill the tables which filling a report.

the best way is to debug the code and see when the datasource class is called....

iam sure the data for ur table shud alwys come from the datasource of ur report.
