I am hoping someone can tell me why the code below is creating an empty pdf file every time?
I am trying to compile, fill and run the xmldatasource sample project that ships with JasperReports 4.0.2. Although I am attempting to do it Programatically as I want to use a similar (non ant-based) compilation method in my own software. The same project that comes with Jasper uses ant scripts to create the report and it works. So I know there is no issue with the JRXML files. However, I cannot seem to fill the report with data correctly.
When I debugged the Jasper engine source to see if my XML source document is being loaded correctly I see that the PARAMETER_XML_DOCUMENT had the value
[#document: null]
Do you think this would mean that the XML source file is not being read correctly?
The code compiles and runs without errors and all of the relevant files are generated (.jasper, .jrprint and .pdf) but for some reason the rendered PDF document appears to have only one blank page every time.
Any help is greatly appreciated…

Map map = new RenderReportBean().execute("northwind", "OrdersReport");

Ok so I found out the issue and it’s a bit of an odd one really as the other means of compiling the templates do not call for the same approach.
The example above uses nested reports and for some reason the runtime compile option requires you to compile both templates individually instead of just compiling the Super report and Jasper picking up the sub-report bu default – as seems to be the case when compiling from ant scripts.
So to make the above code work the line:
needs to be included for each template (super and sub) that are required for the report.
