the problem is that row is a generic object until you cast it i think. I have used this in then past by using syntax like <html:radio ... value="<%=(String)((java.util.HashMap)row).get("VALUE")%>" > Looks ugly but it works.
Note: I have not used it with a HashMap, but have with custom objects like ((com.app.Customer) cust).getName() so i am guessing you would have to cast the get to a string as it will return a generic object as well.

I did a quick test and it seems that having the
<html:radio ... value="<%=row.get("VALUE")%>" > fails
for me too. The output html contains <html:radio ...>
instead of <input type="radio" ...>.
Doing the following worked:
<% String val = (String) row.get("VALUE"); %>
<html:radio .... value="<%=val%> />
Anyway, in general I don't like seeing scriptlets in
jsps. I think your first method looked better to me
with a Collection of beans containing properties. I
think you can then use the following: <html:radio
property="xxx" idName="row" value="value" /> which
will look in the bean exposed by the iterate tag and
use its value property.
Good luck.
