The scope is whatever you define when you declare the variable, exactly like it is
in Java:
<%!
public int aPublicInteger;
private String aPrivateString;
%>
The page compiler just copies whatever you put here into the class it is creating
(so these become instance variables) -- it does not modify (or even understand)
what you are writing.
Even if you declare an instance variable (or a method) to be public, you are going
to have a hard time accessing it from a different servlet or JSP page, because
there is no way (within the servlet API) to retrieve a reference to an instance of
your JSP page. But even if there was, that is really poor programming practice
IMHO -- you should place things that need to be shared in the appropriate scope
(usually session scope for user-related things) instead of trying to access the
"internals" of other JSP pages or servlets.
