Hi Kalya,
First, JSP has it's own list - JSP and servlets have been
differentiated for over a year.
Second, without code snippets of what you are actually trying to do,
it is almost impossible to help. Generally speaking, though, a
NullPointerException causing your code to crash is the result of
improper pre-validation code, like:
if( whatever != null) {
do_something;
}
Cheers!
Mark
