Am I crazy for trying this Certification Exam?

Hello there,

A few weeks ago I decided to prepare this Certification Exam (1ZO-897) because I deal everyday in my work with REST APIs. After clearing both previous mandatories certifications (Associate and Professional) I thought it was going to be useful for my work and for my learning path to achieve this Web Service Certification. However two weeks after I am starting to think about this aim's level of difficulty:

- There are no student's books for this Certification, no guides. This is the only site I found where I can read and take useful information about this Certification Exam and a Study path recommendation.
- Following this recommendation I have already started with the Martin Kalin's book "Java Web Services Up and Running", but I am starting to go mad trying to make run in my local machine the example codes related to Rest Client or SOAP.

And this is the main drawback I find: nowadays it is really strange to see any Web Service or REST API which has not been built with SPRING REST. I know Spring Rest framework is based on Jersey on lower layers... I wanted to study this exam to fully understand the very basics of Web Services but 3 years afterwards it seems I am out of date with these libraries I am reading about on some of this forum topic...

On top of that all of you guys note down the level of difficulty of this certification exam: extreme!

I think I am going to ignore if I am not able to make work the Martin Kalin's example codes on my local laptop (even with the Amazon Access Id and Secret key), I will only use it as a first stage subject reference and I will move on to Mikalai Zaikin's resources (thanks for that). After that I will plunge into Enthuware mock exams which I have already bought them.

I would only want to say that this topic resources seem to me from the last century... I am lucky to have started to work in WS just with Spring Rest and RestTemplate as a Rest Client, Jackson library... Nobody uses now XML... I would also like to ask you if you achieved to run locally the Martin Kalin examples and if you think that few years afterwards of these "primitives" REST and SOAP libraries (JAX-RS and JAX-WS respectively) it is worth to invest all of the time I guess I will have to give for achieving this "impossible" certification exam.

Welcome to CodeRanch Keller.

I do hope that you find the community here sharing, welcoming and knowledgeable.

It does seem like you are on your way with passing the previous two exams, I'll leave the sanity check up to others.
Have you seen this posting from October 2016? It may help you along as a resource or two listed.

Perhaps the OCEJWSD Wall Of Fame can help you out a bit.
Note: I did not realize that there Wall Of Fame for this exam was had so few people listed. For the other exams which there is a Wall Of Fame there are many more people listed.
However in reading some of the stories listed on the Wall Of Fame you may get some much needed inspiration or other information, which could really help you out.

I know that for some other exams some people have started different group chats using something like Google Hangouts or WhatsApp, etc.
I'm not too sure how well that worked out for them, but it is something that you can try doing and perhaps you would find it useful to create/join a group chat.

Please don't get the wrong idea or misunderstand me, I'm not trying to exclude you from using this site in any way shape or form.

Hope this helps you out.
You showed up just in time for the waffles! And this tiny ad:
