Unless you're happy with writing a new setXxx() method that modifies a
collection (which is a clever idea but still something of a hack because
it violates the intent of the JavaBeans specification), it's actually
quite hard to manage collections in this way with JSTL. Since JSTL is
focused on presentation -- on reading data structures rather than writing
them -- it's likely going to be easier to modify collections in a back-end
servlet (or with a new custom tag you write -- one that's specific to your
own custom data).
