marking checkboxes checked from a List

[Rick Reumann <ma...@reumann.net>]

I'm sure there is a good way to handle this in Struts but me being the
dumbass I thought I'd ask for help:

Picture a case where you display a list of "jobs" -
where next to each job name is a checkbox (Just using jobs for this
example). Each checkbox corresponding to the job will have a value
that is a String (jobAbbreviation). Displaying this list of jobs and
the value of the checkboxes isn't a problem ( populated from an
ArrayList of JobObjects ).

The problem is:

How do I mark the correct checkboxes based on an ArrayList of
Strings (jobAbbreivations)? In other words I have just a List of Strings
and I need to mark all the appropriate checkboxes that have the same
values as this List of abbreviations. ( I know an ugly way to do it
using java in the JSP page checking each value to see if it's in the
List but there must be a cleaner way ).

Thanks so much for any help.

RE: marking checkboxes checked from a List

Inside JobObjects bean, add one attribute for checking if this job is
checked, say selectedFlag (Not a good name). Set the value of
selectedFlag to true for all the JobObjects which you want to show as
selected.This you can do in the action class which forwards to this JSP.
While creating the checkboxes, first check if selectedFlag for that
JobObjects is true then display the checkbox as selected.This can be
done using logic:equal tag.
