MessagesTag (Apache Struts API Documentation)

Custom tag that iterates the elements of a message collection. It defaults to retrieving the messages from Globals.ERROR_KEY, but if the message attribute is set to true then the messages will be retrieved from Globals.MESSAGE_KEY. This is an alternative to the default ErrorsTag.

Since: Struts 1.1
