I'm using a report with a subreport.

getMainDataset() return the data set of the main report,

but getDatasets() return null?

Hi

 

getDatasets() returns the sub datasets (as in <subDataset> or JRDataset) of the report (excluding the main dataset) and has nothing to do with subreports. What dataset were you expecting to find in the return list?

 

HTH,

Lucian

I'm expecting to find the query, fields and parameters of the subreport.

You won't.

 

The subreport is specified by an expression whose value is only known at fill time, hence there is no generic way to find out the details of a subreport before fill time. When are trying to get the details of the subreport?

Lucian, my problem is linked to the other message JRDataSourceProvider and Hibernate.

I'm using a no standard way to execute the query.

My query is an HQL string, my solution works fine with only one report, but I've a real problem with subreport.
