A JSP is just a servlet written in a different form. Do you know how JSPs work? The JSP container converts your JSP to a servlet and then runs the servlet. So yes, servlet context and config are also available in a JSP.
In JSPs, there are a number of implicit objects available, including these two:
application - the servlet context config - the servlet config
Fortunately, Jesper doesn't have to - it's been done already. Have a look at section 1.8.3 of the JSP 2.0 specification, and you'll find everything you need to know about implicit objects. [ August 24, 2005: Message edited by: Ulf Dittmer ]
