Head First Servlets and JSP, 2nd Edition

You can walk up, but you can’t walk down...

There’s a getParent() method, but there’s no getChild(). Yet the scenario we showed earlier was for an outer <my:Menu> tag that needed access to its nested <my:MenuItem> tags. What can we do? How can the parent tag get information about the child tags, when a child can get a reference to the parent, but the parent can’t ask for a reference to the child?

Sharpen your pencil

How could a parent tag get attribute values from a child tag? Describe how you would implement the functionality of the cooperating Menu and MenuItem tags.
