Jasper Book is empty.

[Bob.Lawson]

I have two reports, Report1.jrxml and Report2.jrxml.  Both reports work when run individually. 

I have specified  whenNoDataType="AllSectionsNoDetail" so that I will get the header even with an empty dataset.  This works with both reports when run alone.

Now I want to run them together so I created a book and added both reports to the book.  I pass the JRDataSource to each report, but even if I did not I should still get the header.  However I get nothing, just an empty PDF returned.

This is confused. You have a data source and a connection for your parts, but you should only have one of those.  If you're using the same connection as the main report, just use 

 <subreportParameterExpression><![CDATA[$P{REPORT_CONNECTION}]]></subreportParameterExpression> </subreportParameter>

You need to have separate jrxmls for your reports that you are putting in, and then reference them.

Take a look at the JasperReports sample file for books.

http://community.jaspersoft.com/wiki/jasperreports-library-samples

You can also install these samples in JSS, if you are using that.
