>1. Define the modes that you have
>- display mode (for each record I would have a "delete" and "modify"
>images with a link to http://MyServlet?action=<action>
>
>- update mode
> a. display update form and data
> b. update the table data
>
>- delete mode
> a. delete confirmation form
> b. delete the table data
>
>I usually use 1 parameter to figure out the method I want to execute.
> For example I would use "action"
>
>If I want to display all the records:
>http://youraddress/MyServlet?action=display
>
>If I want to modify records:
>http://youraddress/MyServlet?action="modifyform"
>1. The first thing to do is display the existing records
>2. Then click a "modify" button to update the data
>Then the action would be:
>http://youraddress/MyServlet?action="modify"
>
>If I want to delete:
>1. First confirm the deletion
>http://youraddress/MyServlet?action="confirmdelete"
>2. Then actually perform the deletion
>http://youraddress/MyServlet?action="delete"
>
>This way you control what is displayed by the "action" parameter.
>
>Here's the pseudo code:
>
>if "action" is "display"
> call the Display() method
>else if "action" is "modifyform"
> call the DisplayModifyForm() method
>else if "action" is "modify"
> call the ModifyForm() method
>else if "action" is "confirmdelete"
> call the ConfirmDelete() method
>else if "action" is "delete"
> call the Delete() method
