Sundar,
For setting and getting session specific objects:
HttpSession session = servletrequest.getSession(true);//true tells the
servlet engine session mgr to create a session if one does not exist for
this request
Object myobject = session.getValue("my_session_object_name");
if (myobject == null)
session.putvalue("my_session_object_name",new MySessionObject());
For setting and getting servlet specific objects (AKA globals or member
variables):
Object myobject =
getServletConfig().getServletContext()).getAttribute("my_servlet_object_name");
if (myobject == null)
getServletConfig().getServletContext()).setAttribute("my_servlet_object_name",new
MyServletObject());
Hope this helps.
