1. In one of the Questions the "Quiz" name of tag is defined and in options <q:quiz> is refered where q is prefix .
2. Q 46 the correct answer should be e) <% out.print("hello"); %> not d <%= out.print("hello"); %> because use of (d) option is equivalent to this servlet code out.print(out.print("hello") ; in _jspService method which is wrong.
3. Q50 :- "The getAttribute method of the JSP has a return type of Object" this option has been marked correct since a JSP does not have this method rather the implicit objects like request,session,pageContext,application have this method defined .
4. Q61 : - "A redirect cannot be performed after anything has been written to the outputstream" is mentioned as correct option
i think the statement would have been correct if it would have been stated like this "A redirect cannot be performed after anything has been flushed to the outputstream"
The Exam i must say is really really wonderful considering it covers almost everything that we can expect from a good mock exam
