Answer / sanjeev kumar
Information (It can be primitives or objects) can be shared
across different servlets in 3 ways in J2EE.
1) Request object-- If the data need to be shared with in
the request scope we can set it on request object with
request.setAttribute() method. And can be accessed from the
other servlet or JSP with request.getAttribute() method.
2) Session object-- If the data need to be shared with in
the session scope we can set it on session object with
session.setAttribute() method. And can be accessed from the
other servlet or JSP with session.getAttribute() method.
3) Context object-- If the data need to be shared with in
the context (Application) scope we can set it on context
object with context.setAttribute() method. And can be
accessed from the other servlet or JSP with
context.getAttribute() method.
