Hi,

Just to share my experiences today: I failed the scea with 6% below the pass score. I was anticipating this, as my preparation time was about two weeks, and I have little experience with J2EE business components...next time better.

I thought the questions were generally reasonable, and comparable to the findings in other posts. I got relatively many questions on JCA and EIS (which was a bad thing, as I was not prepared for this), and also load balancing and clustering questions (dito). The two hours were just enough for me, so a double check was out of the question.

I have prepared with the certification guides from Cade & Roberts old version, but bought the safari preprint after reading to these posts. In general Cade & Roberts were good, but they lack the J2EE patterns, security threats, encryption, JSF and Web Services. These were all asked extensively. Most of the required info I got from reading these posts and downloading/reading the recommended literature and blogs.
I also bought two practice exams from Sun, which were good preparations. I also have an old certification guide from Allen & Bambera (2001), of which I think the JCA and EIS section will still be approriate. No questions were asked on UML (also not in the mock exams)

I think I should have read an up to date specification/tutorial on Web containers and Servlet/JSP, especially with regard to session management in combination with clustering web servers (two questions)

All in all I think I now have a good preparation for a second time. If I had favourable questions, then probably I would have passed 70 per cent, even without an extensive preparation, but the gradient between passing and failing was steep for me. For the next time, I think I need to concentrate a bit more on:

Connectors/EIS: advantages/possibilities
JSP/JSF/Servlet: comparing technologies in practical applications
load balancing/clustering
security: kind of threats and possible solutions (firewall/DMZ, etc)
encryption: MD5/SHA/DES/DES3/Blowfish
Patterns/J2EE patterns: know them all by heart, including advantages/disadvantages => you can really make points with these
EJB/JPA/JMS..... in practical applications. This also gets a lot of points
JSF/JSP/Servlet: comparison: when to use what: also a source of many questions
JMS/MDB/Web Services/Session Beans: see above
JPA/JDBC/BMP/CMP: pro's and cons

A month should be sufficient...but i'll keep you posted!

Hope this may be of help for others
In this case, I understand the answer (although I symphatise with your frustration). The correct answer is "A", because of the giveaway 'immediate response' and the incorrectness of the other options:

asynchronous messaging is wrong here (see above)
C/D is wrong, because MDBs CAN BE transactional, but this is not necessarily the case, and messaging in itself is unrelated to transactional issues: this is a matter of implementation
Hi Vladas,

By monitoring I mean logging the user's activity on a local web browser. I need to keep track of the web pages that the user is accessing or working with at a certain moment, without interfering with the interaction flow.

Hi,

I want to develop a programme that basically can do two things;

1: monitors regular browser interaction so that the programme knows which web-page is current at a certain moment
2: Allow the user to enter data from a browser and which uses the current web-page that was monitored.

Intuitively, I would think that I have to split up my application in an applet that implements a toolbar or so(for the second function), and a client that listens to port 80, or somehow implements an internet socket to monitor this information.

My question is if this is indeed the best way to tackle this problem and if there are some good proven solutions in JAVA to monitor browser interactions.

Thanks,

Kees

Hi,
I am trying to do the SCWCD exam on the other wrox book, namely "Professional JavaServer Programmin"g" J2EE 1.3 edition. Is it correct that I should be concentrating on the chapters over servlets / JSP (chapters 5-12) to do this?
I have the feeling that I would be doing a superset of the requirements anyway...
Thanks,
Kees
Do you recommend this book for a JSP newbie?

I am using DefaultTable model, because it provides most implementations I need. I just need to override one or two methods. The abstractTableModel was much more basic
