Newbie - session/request object at class level ?

[ultan o'carroll <ul...@totalise.co.uk>]

Dear All,


Im getting errors when I try to use a tag library that Im developing
(trying to develop I should say)
telling me that I have "undefined variable or class names" (sepcifically
request, session, log)
when I try to use these objects in the class level logic element of the
library (see <!-- ** here ** --> comments )-

  I understood that these objects were made available in XSP thru
wrappers and that I could call on HttpServlet superclass methods such as
'log(String)' ? Am I
  doing something wrong, got the wrong end of the stick, or do I need
a   holiday ? (If I get this going I should be a millionaire by the end
of   the week)


  Thanks in advance -
