In this article I’d like to explain two things. First, what to do when you want to restrict JAX-RS providers to be used on, for example, client-side only. And second, what are the issues (and how to solve them) with injecting providers when you create and register instances of them directly.

Sometimes it would be nice to have a possibility to wrap a resource method call. Imagine a use-case in which you need to process business code, placed in your resource method, in a transaction (open transaction before resource method, commit or rollback transaction at the end) or apply some advanced security constraints. If you’re using JAX-RS together with CDI in your application it’s not a problem to do such things. Fortunately, with Jersey it’s also possible to do those things outside of CDI.
