Detecting/Displaying Empty Jasper Report

2006-03-15 05:59

Hello - I am using Hibernate as a datasource, and when the SQL query returns no rows I get back a blank Jasper Report (no headers, no nothing). Is there a way I can get Jasper to either 1) still print the headers or 2) Print out a message saying that the user's query returned no rows?

 

In addition, my reports have an HTML link (via a variable I set) back to the Reports Selection page, but this link does not show when the report is blank. I would have expected Jasper to still print all of the other report elements, but just not have any rows of data.

 

Thanks for your help

David
