How to create in-memory JRDesignSubreport?

2006-03-24 10:40

hello,

 

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 :)
