You can do this on your own custom objects.  When encountering a
Collection, however, the JSTL EL (and the preliminary JSP 2.0 EL) treats
it as a Collection, not a JavaBean.  Thus, the JavaBean properties you add
to the Collection via a BeanInfo class have no effect on the EL.

The ideal thing to do, if you're designing your own data model, is to
provide a wrapper for the Collection that looks something like this:

  public Collection getItems();
  public int getSize();
