Hi,

I feel the following are the answers for HFSJ Sharpet your pencil Page 201.
Context-scoped attributes NOT thread-safe (already chcked)
Session-scoped attributes NOT thread-safe
Request-scoped attributes Thread-safe
Instance variables in the servlet NOT thread-safe (these can be changed by other threads)
Local variable in service methods thread-safe (bcoz local)
Static variables in the servlet NOT thread-safe (similiar to instance variables except static)

I think first 2,3 answers are correct. what abt last three? Can somebody correct me plz?
