It's indeed too late for JSTL 1.0, though we realize it's important and
will probably address it in JSTL 1.1/JSP 1.3. The best workaround, when
you're a Java programmer, is to provide all data the page authors will
need yourself; e.g.,
public class MyData {
Collection collection = ...;
public Collection getCollection() { return collection; }
public int getSize() { return collection.size(); }
// accessors useful data other than size
}
Glad to hear you're enjoying JSTL, though! Thanks for the note.
