Restrictions

If the name attribute is not specified then uses a parent bean tag to locate the bean on which to operate. The property attribute should be used to specify what to retrieve; if not specified then the bean object itself is retrieved as a string. The id attribute specifies the name to save the retrieved property as; useful for non-string properties. If the eval attribute is specified then the value of the attribute is evaluated and written to the page output; this replaces the bean processing described above.
