You will need a file upload page to allow the user to send the file to the webapp. You will need a CSV parser to convert the CSV data into java components.

On the display page:

To display the CSV plus checkboxes in a dataTable, you'll need to define a suitable row model object, which can be something like an aggregation of a binary property and a row of the converted CSV data. These row models would then be assembled into a collection, which would then be wrapped with a JSF DataModel object (such as a ListDataModel). Pre-checking the checkboxes can be done by simply setting their corresponding row model object properties to "true".

You do NOT send parameters from the checkboxes. JSF is designed to work with server-side Model objects, not parameters on the View. If you want a button on the webpage that does a "select all" function on the checkboxes, write an action method for a commandButton and make that action method enumerate the row models and set their boolean checkbox value properties to true.
