NullPointerException is thrown by an application whenever it uses null, at a
place where it expects an object.
For example ,you may be trying to use a method of a object which is null, or
may be trying to modify some fields of that object.
In such cases it may throw a nullpointerexception.
A JSP may be expecting a parameter to be passed from a previous JSP or may
be an HTML.
String BWavailable = request.getParameter("BWavailable");
However if this JSP does not receive any parameter by this name, then it
will throw a nullpointerException.
Hope this helps,
