dynamic property access

[Ben Anderson]

Hi,
I want to dynamically set which property I access.  Is this possible? 
Obviously the below code won't work, but you get the idea.  I thought
maybe that the <j:expr> tag might help, but it doesn't seem to do
anything.

    <j:set var="color" value="red"/>
    <j:set var="colorKey" value="color"/>
    <ant:echo>
        ${${colorKey}}
    </ant:echo>

Any ideas?

Thanks,
Ben
