You've been spoilt by other taglibs that hunt around for your object. In
displaytag you have to tell it explicitly where you've put it. By
default it looks in requestScope which is why your first try worked. If
you put the name="sessionScope.attendeeVector" attribute into the
<display:table> tag then it should be able to find it.
