SelectBooleanCheckbox and entity deletion in DB

Question

Hi,
In HtmlDataTable i am displaying entities from DB , and i am associating a checkBox to each entity(dynamic for n nuber of entities), when user select on a check box that corresponding entity i have to capture in Backing bean to make deletion.
There is no relation ship between checkbox and entity displayed in data table( i can't associate coz im getting Data Layer from another person). is there any way to do this .
