public class SetTextPropertyTagLib
extends javax.servlet.jsp.tagext.TagSupport

This class handles the setting and changing of language properties objects in the users session.

• If the request includes a LANGUAGE parameter, the requested language (value of the language parameter) Properties object will be set in the session.
• If there is no text file set in the session and there is a ProfileCookie present the language will be set to the value returned by ProfileCookie.getLanguage().
• If there is no language parameter specified and there is not already a Properties file set in the session, the Properties object will be set to English.
• If there is a change of language, the language is being set for the first time, or there is no ProfileCookie present, a ProfileCookie will be sent back to the client.

The Properties file referenced in the session by the TEXT key contains the text for the page.

For this class to work there:

• must be two Properties objects containing the applications text set in the ServletContext, one French the other English, that can be retrieved using the name TEXT with the method ServletContext.getAttribute(java.lang.String).
• may be a parameter passed in the HttpServletRequest which has the name LANGUAGE and the values ProfileCookie.EN or ProfileCookie.FR. If it is present the users language will be changed to its value.
• may be a ProfileCookie present in the request. If present the user's language will be changed to the value returned from ProfileCookie.getLanguage().
