What are you trying to achieve? Maybe you're trying to put logic in your JSPs that more properly belongs in an action.
thanks. what i am trying to do is to get the value of a field. Say I get a list of items: class item { Set values; ... } The item has a set of Values: class Value { Attribute attribute; String value; } What I wanted to do is to get one particular value based on attribute ID. in this case I have to add a method in the Item class, someting like this: String getValue (String id) { while (it.hasNext()) { Value value = (value) it.next(); if (value.attribute.getId().toString().equals (id) return value.value; } So from JSP, I would like to call this method <c:out value="${item.getValue (id}"/>
