Tag handler class is not a servlet or jsp, so it doesn't
have access to many implicit objects which are available in
jsp. It, however, has a reference to PageContext using which
we can call :
pageContext.getAttribute(name) // looks in page scope only
pageContext.getAttribute(name,scope) // looks in specified
scope
alternatively we can also also get references to other
scopes using :
pageContext.getRequest()
pageContext.getSession()
pageContext.getServletContext()
pageContext.getServletConfig()
And yes, this pageContext implicit object is given to the
tag class by container, during initialisation of this tag
class when setPageContext(PageContext) is called by container
