Hi :-)
ServletContext().setAttribute(...) and ServletContext().getAttribute(...)
are "a pair", we can sut/get some "context/myapp range" objects into/from
ServletContext() with this way.
if you want to get servlet context init parameters, I think we can use:
- set them in:
% server.xml
% ?context-param> in WEB-INF/web.xml -> I study it from your
email(Email.this) just now, I didn't try ^_^
- get them with: ServletContext().getInitParameter(...)
