Re: JSTL: getting a map's keys

I was thinking along the lines of this incompletely worked-through notion:

public class ContactScreenBacker
{
private final Map<String, Rate> rates = howeverYouSetItUp();
public Map<String, Rate> getRates() { return
Collections.unmodifiableMap(rates); }
public Set<String> getKeys() { return
Collections.unmodifiableSet(rates.getKeys(); }
// ...
}

You should be able to use an EL like '#{thingie.rates["Bill"]}'. I
haven't tried it, but this is what I had in mind.
