How can I format the date list in struts 2 select tag?

I am trying to format dates in struts 2 select tag, but I am having difficulty with this. I know there is a struts 2 tag label, but I don't think this is what I am looking for.

What I am doing here fills the selection box with a list of dates (days off) where I can choose which dates to add to the employee’s time sheet. Basically I try to format them so that they appear nice and neat (MM / dd / yyyy), but I can't find the right way to do this. I tried inserting a format tag between my list below, I tried using the format.date parameter in the tag, and I tried using listValue to format dates, but nothing works. Did I miss something?

<s:select size="25" id="inputExclusionDates" name="available" list="availableExclusions" multiple="true" cssClass="multi-select" />
