EL expression evaluation

Hi folks!
I'm invoking my servlet through link = http://localhost:8080/test.do?evalparam=duck.name .
test.do servlet adds an attribute "duck" of class Duck (JavaBean with "name" property) to request scope.
Then I forward a request to test.jsp page.
What I want to do is evaluate parameter evalparam=duck.name to EL expression.
I know that I could do this by spliting evalparam parameter to two parts part1="duck" and part2="name" and then invoke ${requestScope[part1][part2]} but I'd like to do it through some kind of evaluation mechanism, e.g. ${evaluate(evalparam)} to acces property. And I'd like this mechanism be property chain independent.
Do you have any suggestions?
I'm considering creating tag which would evaluate this expression but is there any easier way?
Thanks a lot,
Cheers,
Maciek
