Variable number of fields in a Struts Form

[Paul Blundell]

I have a Struts form which can contain zero to many instances of a set of
fields (depending upon the number of rows in database table).

For example:

row1field1  row1field2  row1field3

row2field2  row2field2  row2field3
    .             .          .
rowNfield2  rowNfield2  rowNfield3


So when the form is submitted, all fields will be correctly updated in the
Form bean/Form action.
The number of rows will be dependent on a database table - there can be a
variable number of rows.

I've never implemented a form containing a variable number of fields, so my
questions are:

1) How to I define the ActionForm Bean to store these multiple sets of data
(can I just use arrays?)
2) How do I output the fields (text) in the JSP (do I use the Iterate logic
tag?)

I'm not concerned about how I go about reading/writing this information
from/to the database, I can figure that out for myself, its just getting an
example which demonstrates the above.

Thanks
Paul
