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.

But it is still ok to practice with RestEasy. The basic concepts of both RestEasy and Jersey are more or less the same.
Ulf Dittmer wrote: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.
Ulf Dittmer wrote:Jersey is the RI. Since the objective is JAX-RS, though, I would imagine that any conforming implementation would be fine.

Ulf Dittmer wrote:My first question would be: why are you not using a REST framework like Jersey? Implementing all those low-level parts is a lot of work that other folks have already done for you.

Holder<OperationRequest> operation_request = null;
You must define the operation, which in this case would be the ItemSearch I think.
