Hi I am using Head First Servlets & JSP 2nd Edition and given Final mock exam.

I am very much disappointed by the exam lots of errors I found and some of them are very Big mistakes, in order to confuse reader given very close answer which is good but some questions right answer is not selected .

Big mistakes
===============================================================

66.

Question is given with two para and no options are there to select ???
Page 824

26.
Answers given B,D seems by mistake because in comment of answer it self its written Answer A,B,D make list not empty.
So <c therwise> will not execute So correct answer is C,E but checked wrong answer.

45.

Assuming that �my.jsp� adds bytes 4,5,6 to response ,what is the result ?
A.123
B. 456
C.123456
D.456123
E.An Exception is thrown

Anser given : B.

The first mistake here is line no 15 is wrong it should be request.getRequestDispatcher();
Also If you correct this mistake and run this program in tomcat its giving you IlleagalStateException .
Correct answer is E


49.
Answer checked is against the comment given.


Here Line 3 is wrong because prefix jsp is reserved for standard actions. ( D should be answer)

69.
Here we have two directories (directory 1, directory 2)and two members (Beginner,EXPERT). And inside Security-constraint only http-method is given which is �GET�. Now we want to restrict BEGINNER to access directory 2.
Anser Given (D)
As per answer given is to put directory 2 url and role tag BEGINNER.

Which is equivalent to :

It means BEGINNER only can access directory2. ( Which is completely against the question asked which want to restrict BEGINNER to access directory2�s resources)
As per me answer is C.

===============================================================
Small mistakes
===============================================================

6.
Answer C : The DD tag used to declare them is : <listner> is also true�.

14.
Anser B : Java EE containers must support URL rewriting is also true .

Comments given with the answer � URL rewriting is almost used as fallback when cookies are not available ,but its NOT a requirement for containers�

I feel its wrong even if it used as fallback container must support it�


54.
I tried this example in tomcat even if you put <exception-type>IOException</exception-type> container not giving any validation error.

Anser given is A. is only ture if B is not given because if both are there correct answer is B. Which says If application throws an IOException ,nothing will be served.(Because in DD we didn�t give comple class name of IOExceptin.

60.
D. Both (context parameter,servlet init parameter) can be directly accessed from a JSP
Here option D is not given true.With Imlicit object application,config we can do that.

Thank you for sharing your errata with all ranchers. Just to clear something up, some authors are kind enough to be around at the ranch, but don't expect them to react to your requests They may not even see your post. If you have an errata to share to the authors, post it at the publisher's home page.

Hi,
Can someone confirm answers suggested by Gopal.

I checked the errata on the site, but confirmed errors section is blank.


Confirming these errors/answers will sure help Ranchers who uses HFSJ Coffee Cram exam as a barometer for real exam. Errors in this coffee cram can confuse the person who is taking Coffee Cram when he is ready for exam as suggested by authors.

Thanks
Sandip

Hi Sandip,

I too posted/reported some of the errors from coffee cram but no response. I do agree that there are a lots of errors and some of the questions are missing answers to choose from.

I just suggest to keep posting these on this forum and you will get the answers from the co-ranchers.

Thanks and good luck,

Naveen Katoch

In that case, it would be better to post them one by one, not in a bulk.

Thank you Gopal for posting these errors.

I was also surprised that authors/publisher listed *no* errors.

I have found other errors, but have not reached test yet.
