Question :-

Your web application uses a simple architecture in which servlets handle requests and then forward to a JSP using a request dispatcher. You need to pass information calculated by the servlet to the JSP; furthermore, that JSP uses a custom tag and must also process this information. This information must NOT be accessible to any other servlet, JSP or session in the webapp. How can you accomplish this goal?
Store the data in a public instance variable in the servlet.
Add an attribute to the request object before using the request dispatcher.
Add an attribute to the context object before using the request dispatcher.
This CANNOT be done as the tag handler has no means to extract this data.
