Hi Folks,

I have a requirement in which I have to create a JSF Datatable which will fetch data from a HashMap<String, ArrayList> where the Key corresponds to the column name and the value will be an ArrayList of data for the column.

As of now I have two columns EmpName and EmpNo.

Here is the POJO/Bean Class:

Here is the backing bean:

Now how do I go ahead and construct the dataTable so that it picks up the Key as column name and Arralist as the data in the column.

Please provide your suggestions and code snapshots.

Help is appreciated.
