variable in scriplet and declaration

[Nelson Nadal]

The variable in declaration code is member variable(instance), isnt it? Then why is it said that when two user making requests to the same JSP can change the value of the same variable?
It also said that if I want the variable to be different for each request I should put it in scriplet code, this must be the instance or static?
Thanks again for enlightment....

Variables created via a declaration are indeed created at the class level as instance variables. Since the container will share a single instance of the servlet created on behalf of your JSP (as other servlets) across threads, each thread executing the JSP will 'see' the same variables.
When the variable is created in a scriptlet, the declaration is within the body of a method and therefore has a unique (stack) instance for each thread.
