You can encapsulate the objects within a JRBeanArrayDataSource or JRBeanCollectionDataSource and access the elements of the objects as fields. The inner contactList is best suited for being used in a sub-report (just off top of my head, this may not be the case depending on your report design), you would pass the sub-report a datasource expression of "new JRBeanCollectionDataSource($F{contactList})"
