Struts tip o' the day ~ using bean:size A co-worker turned me on to this one today - you can use <bean-el:size collection="${myForm.list}" id="listSize"/> to get the size of a collection and expose it as a pageContext variable. I've been looking for this sucker for years! Usually, I end up putting a getListSize() getter on my form to accomplish this, since none of the other tags (including JSTL) allow you to get the size of a collection.
