    Question Implementing Custom Fields

    Hi all --

    I am working on a Contacts Manager application and want to be able to give our users the option of defining custom contact fields.

    E.g. The standard Contacts table could have the following fields: Name, Address1, Address2, DOB, Email

    But Tom wants to add 2 custom fields, so he has: Name, Address1, Address2, DOB, Email, [Salary], [Region]

    ... and Mary wants 3 custom fields, i.e. Name, Address1, Address2, DOB, Email, [Height], [Weight], [InsideLegMeasurement]

    I wondered if anyone had any ideas how this might best be implemented in java? Would XML be the best choice for the table definitions? Would I have to create new DB tables on the fly for each user based on the table defs, or have a large 'standard' table capable of accommodating several custom fields?

    And I'd like to evaluate who's logged in at runtime and display the appropriate data in a JTable. Would I need to extend AbstractTableModel for this?

    Sorry for all the questions, but I'm pretty new to this. Anything you can do to help would be greatly appreciated!

    Are you connecting to a SQL database, or are you just making your own?
