About Question enthuware.jwpv6.2.790 :

[koitoer]

The question is "Which of the following attribute scopes are thread safe".
The marked answer is "Local variables", but as far I know local vars are not defined in any attribute scope, I agree with the explanantion, but not with the answer, probably better answer should be "None of the above".

It is an error?

[admin]

You are right. Servlet instance variable and local variables are not technically "attributes". The problem statement has been updated to state both.

thank you for your feedback!

it seems that the old version of the question is back :

Which of the following attribute scopes are thread safe?

local variable can not be considered as "attribute scope"

[admin]

I see that it says "..variables and attributes..." instead of just variable.

HTH,
