How to create in-memory JRDesignSubreport?

2006-03-24 10:40



I`m trying to create a JasperDesign in-memory with several SubReports.


JRDesignSubreport designSubreport = new JRDesignSubreport(styleProvider);



Now I want to set the values for:

- "DataSourceExpression" and the

- "ParameterMapExpression"


I can`t figure out how to pass a HashMap to the method


- designSubreport.setParametersMapExpression(...);


and an Object implementing the interface JRDataSource to the method


- designSubreport.setDataSourceExpression(...)



Both of them needs a JRExpression as a parameter and I don`t know how to use this....

It would be very nice if someone can help me :)
