I would like to get Web-Service-certified and I have been reading a while about certification paths on the Oracle website: Oracle Certifications
I have found two certificates of which I can not seem to determine the exact difference, and more personal, which one I should choose.
First there is 1Z0-862 / CX-310-230 which seems to be the basic exam for the Java 5 platform.
But then there is also 1Z0-897 / CX-310-232 which, I assume, is the equivalent for Java 6?
Does anyone know what the differences are, and which one I should choose (being SCJP 1.4 certified, having a lot of experience with Java 5 and web services).
Also I am looking for an appropriate exam book. I mean a book which is specifically written for those who want to take the exam, not just about Web Services.
As far as I know there isn't a book specifically written for this cert, Amazon has one you can pre-order but it's been "coming soon" for over 18 months now and is out of date before it's even released (if it ever does get released!). There are some notes knocking about written by Ivan and Mikhail which are your best bet - see thre FAQs.
As for the versions, I don't know, let us know when you find out!

I recently got a reply from Oracle University (in The Netherlands). They basically suggest that 1Z0-897 (the second one in the list of suggestions by Ganesan hereabove) is the lastest version and the one to go for. To me it seems it covers more (recent) topics.
From my personal experience, if you are studying for an exam that is not the latest version, try to go for that latest version instead.
Still the question remains which are good (e-)books for preparation.
I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link: http://aspose.com
