jspInit is called before anything else happens. Naturally, don't expect to see
beans imported using useBean in the body of jspInit.
See section on Implicit objects in the spec. It says these implicit objects are
accessible only withing scriptlets or expressions, not withing declarations or
jspInit().
You can use the Servlet API to get hold of the "application" object like this:
getServletConfig().getServletContext() in jspInit().

They should be the first time or every time depending on the scope. If they are
not, send me a simple page and bean and I'll check this with JSWDK 1.0 final and
fix it if necessary.

See the JSP 1.1 spec; it is moving in this direction. Pre-initializing beans is not
something we've looked at: its not very expensive especially compared to JSP page
generation and compilation.
