Short answer: yes, no problem at all.

My guess is that it's just a naming issue. It looks like you're trying to
use the property "longValue" as your sortProperty, but then within the
column, you're referring to "Long". So which is it? If that's just
something that happened because of genericizing the code, that's one
thing, but those should be the same. The question is, what is the name of
the getter function that will give display:tag the value to be sorted? If
it's "getLong()" then you should refer to that as "long". If it's
"getLongValue()" then you should refer to it as "longValue". In BOTH
cases, the property on which you'll sort should be the same. In the code
below, I'm assuming that it's "getLongValue()":
<display:column titleKey="Year" sortable="true" sortProperty="longValue">
<a href="<c:url value="/person/listantigosalunosbyclass.do">
<c:param name="class" value="${longValue}" /></c:url>">
<c:out value="${longValue}" />
</a>
</display:column>
Hope that helps...
