Well, all you're doing inside the loop is adding hidden fields. By definition, hidden feilds are... hidden. Also, have you checked that there are indeed parameters in request? Print something, debug.

You are already iterating the array in the 2nd loop so don't you just need:<input type="hidden" value="${paramValue}">
