Need Help:How to port HashMap<String-ColmnName, ArayList-ClumnData> to Datatable for multiple colmns
posted 6 years ago
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.
