My experience on the exam

I passed the exam today at 98%.

I missed one question in "endpoint design and architecture" section.

Though the score is nice to me, I think the test is more difficult than what I had expected. (for me, the preparation time is longer than the time I spent on SCEA part I)

This is because when I am working on mock exams, for example,, it is likely that I can point out the correct answer(s) immediately, but in the real exam, for several questions I should study each choice carefully, and guess a best answer.

4 or 5 drag and drop questions in the exam and many questions on security.

The exam do cover some level of code details and APIs, but appear only in choices and drag and drop items.

I don't think it's required to practise writing code when preparing because it may make me distracted to vendor specific details (for example, axis), I must confess that I haven't written a single line of code using web service technologies till now.

Repeat mock exam again and again because this will make you confident that you'll get a score higher than 90%

Read MZ's guide & Quiz thoroughly, which make me confident that I should have a 95+ score.

SCJP: 88%<br />SCEA Part I: 95%, Part II/III: 95%<br />SCDJWS: 98%

Congrats Sanly!! 98% indeed is an amazing score in SCDJWS.

I am also be appearing for the Exam on this weekend so any kind of suggestions are most welcomed.

I am worried about the JAXR, JAXB, JAXP API's and a bit on Security and Design questions.

Also could you confirm me if any of the mapping files and their structures are asked in the exam?

hello Dinesh,

For JAXB, JAXR, JAXP, you need to be familar with the API, at least the basic steps for manipulating an XML document, also the high level concepts may be questioned in the exam.

The security questions will be asked at a very high level, for example, you may not be asked the implementation details of a specific security specification, but you should know the purpose and general functionalities for each security spec mentioned in the objective goals, for security section, I think reading MZ's guide and guide is enough.

The design questions may be in the form of a scenario, it seems the most relevant reading material is sun's blueprint.

No questions on mapping xml details in my test, but you need to know where to configure (in which xml file) a specific kind of information and the deployment structure (where to put the config files).

Thanks Sanly for a prompt reply,

I have read the MZ Notes & xyzws for security related stuff, also know how to identlfy the kind of design pattern application for a particular scenario hope I nail them in the exam too but not really confortable with the tones of API's for a single exam.

Also we need to know the complete structure of web.xml for (JSE) ejb-jar.xml for (EJB SE), JAX-RPC mapping files and webservice.xml file?

Dinesh, I don't think it is required to remember all xml details, but given a specific feature, you need to tell where it is configured, for example, which xml file is used for setting up handler chains? Also it's necessary to know the basic structure of the config xml, for example, element order, what's the parent, child. Anyway, it seems practical to remember details about WSDL but have a general knowledge on the structure of deployment descriptors, mapping files.

design pattern questions in the exam is very simple and straightforward, it covers only 6(?) patterns mentioned in the exam objective

Client side: business deligate, service locator, proxy
Server side: web service broker, facade, adapter

That means, what you need to do is to understand the question, determine which side(client or server?) the question is asking, then pick up an answer from the three.

If still not confident with the design pattern section, repeat mock exam again and again, that will make you confident.

Good luck!

I am also looking forward for SCDJWS, but have no experience on it.
Can you guide how to kick start?

I started preparing the exam by reading RMH book (java web services), and I do think this is a must read for the guys with little on-hands experience on web services technologies like me. I read the book very carefully even if the topic is outside the exam objectives, anyway, I was trying to learn web services systematically rather than just got sun-certified.

Besides this book, sun blueprint is a must read.

For higher score, you may need to read other resources, for example, WSI BP1.0a, j2ee tutorial (relevant chapters), guide, mocks, MZ's guide & quiz.

I have read all books and resources that mentioned above, some of which I read twice.

That's fabulous score buddy

I'm really inspired with that score . I'm exactly in a position where you were before taking the exam, I mean, I have little hands-on experience on Web Services. Can you please tell me how many hours of time will it take to prepare thoroughly (Ofcourse to achieve great scores like you

So as to boost up my study, I'm really looking for study parters. Currently I'm not even spending 3 hours strictly per day

Thanks and Regards,
