Hello Everyone,

I am preparing for the OCEJWSD certification.When it comes to JAX-RS which is the Reference Implementation that is better to study from a certification point of view.It is RESTEasy or Jersey?.

Thanks,

Jersey is the RI. Since the objective is JAX-RS, though, I would imagine that any conforming implementation would be fine.

Well ... I'll let the experts answer that. The Exam Topics (which I'm sure you've read by now, short as they are) mention "Create a RESTful web service in a servlet container", amongst other topics. That could conceivably involve deployment steps that are implementation-dependent.

For this exam, focus on Jersey API. Someone mentioned in this forum that reading the latest Jersey User Guide (version 2.8) from Chapter 1 -5 will help.
But it is still ok to practice with RestEasy. The basic concepts of both RestEasy and Jersey are more or less the same.

In other words, not the Jersey API, but the JAX-RS API :-)

The only disadvantage you have when studying RESTEasy for the WSD exam is for coding Web Service client. The exam topic "Create a web service client for a RESTful web service" assumes you have some basic knowledge coding a Jersey JAX-RS client.

For the exam you can stick to Jersey 1.x (as it conforms to JAX-RS v1.1). If you read the Jersey 2.x manual you willl learn a lot of stuff that is not part of the exam (as it conforms to JAX-RS 2.0).

Here is the link to the Jersey 1.18 manual.

Regards,
Frits
