When i click on Fetch button, I need to get all the employess belonging to a particular department from database, And i have show them up in a table in the same page. This part i have done. Once i get the employees i should be able to edit any employee details and click on Save button should save these details in the database again. Since each department will have many employees, when i click on Save button how can i propagate all the updated entries further (to my action servlet)? It would be helpful if you can provide me some example code for this scenario.
