What is the exact error message?
Have you actually put something there before you tried to access it? Ask
whether what you get from the servlet context is not null first and then try to
cast it if it is not null.
(I don't know the exact class names)
sContext.setAttribute("com.javaechnage.DatabasePool",DatabasePool);
DatabasePool dPool =
(DatabasePool)sContext.getAttribute("com.javaechnage.DatabasePool");
