If you have indivicual checkboxes that Are of the true/false variety, and each indicate a separate boolean value, use <html:checkbox>
If you have a group of checkboxes that allow a user to select one or more values from a list of values, use <html:multibox>
Each of these tags will cause Struts to populate an ActionForm bean property that you can read once the page has been submitted.
