The best solution IMHO is to mimic/steal the way Swing does it.
Instead of using an ArrayList, create objects that implement the swing
ListModel or TableModel interfaces.
That way, it's also very easy to create nice debugging/admin apps with the
same components (remember, reuse is what it's all about). And then you
create your JSP helper classes (might be beans, might be tag library) to
convert create the 'Views' for your models.
It's not that difficult to create a class that uses the swing.TableModel to
render an HTML representation for it. Same for lists. Create HTML components
to convert the ListModel data to comboboxes, <UL>, ...
Since we're on the subject, you might take it one step further and create a
jdbc RowSet implementation that also implements the swing TableModel
interface. This could be really the summum for web development. And we're
talking about completely generic components here.
I'll be doing some of these things as well. I'll try to keep you updated.
Good luck,
Geert
