Tag size

Define a bean containing the number of elements in a Collection or Map.

Given a reference to an array, Collection or Map, creates a new bean, of type `java.lang.Integer`, whose value is the number of elements in that collection. You can specify the collection to be counted in any one of the following ways:

- As a runtime expression specified as the value of the `collection` attribute.
- As a JSP bean specified by the `name` attribute.
- As the property, specified by the `property` attribute, of the JSP bean specified by the `name` attribute.
