Or, since you're using the core JSTL library, you should also have access to
the format library, and you can use 'fmt:formatNumber' instead of 'c:out' and
do the formatting there.
Probably, an even better alternative would be to use the or 'url' attribute of
the <column> tag itself, and put your "value=${...}" inside the <column> tag
too; in that case, you should be able to use the 'format' attribute as desired.
Your tag would end up looking something like:
<display:column class="numbercell" title="Budget Line Balance Amount"
total="true"
format="{ 0, number, currency }" url="glBalanceInquiry.do"
value="${row.currentBudgetLineBalanceAmount}" />
Also, your <a> tag should have href="glBalanceInquiry.do" target="_blank", so
the browser knows you're using the 'target' attribute.

Displaytag is trying to convert your entire href string into a number (which
it/java obviously cannot do). I notice that you're not using the property
attribute on the tag; you may have to use that with a decorator to get the
desired effect.
