HFE p364 q9 and Single point of contact for HEF errata

I may be missing something here, but the answer(p369) for question 9 (p364), chapter 6 in Head First EJB says you can call getEJBObject() from within EJBCreate(). Page 179 of the EJB spec lists getEJBObject() as callable from EJBPostCreate() but not from EJBCreate().
Also, in trying to find out if anybody had encountered this before, I found that trying to search HFE errata here is daunting; everybody's using slightly different ways of expressing mock exam references, and even the title of the book ("HFE", "HF EJB", "Head First EJB", etc.). Somebody may already have hit this issue but I can't spend all day searching here to try to locate it.
(Lest anybody get the wrong idea, I *love* Head First EJB, and Kathy and Bert's SCJP book got me though that exam too. But anything this big is gonna have some glitches in it.)
Kathybert: Is there a preferred central reporting point for suspected HFE errata? During my study I've bumped into a few obvious typos I'm sure you'd like to clean up. And it would be great if there was a single point where we could easily find officially confirmed errata for the book.

poop. Of course the subject was supposed to read "...HFE errata".

Below is the offcial o'reilly link for the book. The errata link opens the official errata submission page and it also containes the list of confirmed/unconfirmed list of errata and they are sorted based on page numbers. Also you can download the answers for sharpen your pencil excercies from there.

You can see in that list someone has already submitted that error for Pg 369

Howdy Maggie,
That's *definitely* an errata--you can't call getEJBObject() from ejbCreate(), because the Container doesn't know the primary key value until *after* ejbCreate() completes, and it needs that value before it can make the EJBObject.
I REALLY thank you for going so *easy* on us for the errors in this first printing... it definitely has, well, "glitches" as you euphimistically call them
With Head First Java and Head First EJB, they represent the first books of this type, and they aren't produced through any normal publishing process--they are more or less hand-built and graphic, so even things like running them through spell-checkers are virtually impossible. We are trying something completely different to improve the process for our next books, but that doesn't help with EJB.
So, we just hired someone to build a master document of the HFEJb errata, to make it much much easier to figure out. This document will take care of everything that is on the O'Reilly errata, confirm the unconfirmed, etc. and be much easier to read. And the next printing will have all the corrections made. The guy working on this is someone many of you know, because we found him here... Keith Rosenfield. We picked him because, well, he's the pickiest person we found, and has been perhaps the most vocal, um, *complainer* (in a good way ) because he wanted to be very careful in his studies. He recently passed with a 95%, so his persistence paid off.
Anyway, once again, thank-you Maggie for being so tolerant. I'll post here the MOMENT the revised errata document is complete. Should be very soon.
In the meantime, cheers and good luck,
Kathy

Sudhir: Thanks for the O'Reilly URL...I'd gotten into the habit of thinking of www.wickedlysmart.com as being "the site" for Kathybert books; especially since the first one I used was an Osborne rather than an O'Reilly. (The "Shrapen Your Pencil" answers are at Wickedlysmart too....maybe some crosslinks are in order).
Kathy: Thanks for your reply as well. I've been promoting your books among people who come to me for advice on studying for certifications. The "Head-First" approach (which the SCJP book also follows to a certain extent, although perhaps not with the delightful gay abandon of the others!) has been sorely needed in our field; not everybody is prepared to cope with the additional mental workload imposed by more traditional presentation styles. Besides, if this stuff can't be fun too, there's something wrong. :-)
Further, I'd *much* rather have HFE {in hand now as it is} than {with every tiny blemish polished away four months later}.
Cheers...

If anybody could find errors in the book even after the next 6 months, then it has to be Keith Just kidding, congrats Keith HF EJB was one of the best technical books that I have ever read, and might continue to remain so...
 
I agree. Here's the link: http://aspose.com/file-tools
