JRTableModelDataSource question

[bdteter]

I am having some issues geting a Jasper Report to work using a JRTableModelDataSource. 

My data model is a 2-D array of objects.  I have fields setup in the Jasper Report that have the same names as the properies in the object that I want to print (the object has additional properties).  But when I run the report from my application I get a bunch of expections "net.sf.jasperreports.engine.JRException: Unknown column name: name..."

Do I need to put my data in some other format so it is compatible with the JRTableModelDataSource?

Here is the source of the report:
