The set of ThreadLocal instances associated with a thread are held in private members of each Thread. Your only chance to enumerate these is to do some reflection on the Thread; this way, you can override the access restrictions on the thread’s fields. Once you can get the set of ThreadLocal, you could copy in … Read more
The problem was the lack of whitespace before the colon: @Path(“/mypath{param1: (/param1)?}”) should be: @Path(“/mypath{param1 : (/param1)?}”) Apparently it’s a bug, because the specification makes the whitespace around the colon optional. I also found that I’m not the first bitten by this bug.
An entity manager can only be injected in classes running inside a transaction. In other words, it can only be injected in a EJB. Other classe must use an EntityManagerFactory to create and destroy an EntityManager. Since your TestService is not an EJB, the annotation @PersistenceContext is simply ignored. Not only that, in JavaEE 5, … Read more
You can create filters and easily bind them to the endpoints you need to log, keeping your endpoints lean and focused on the business logic. Defining a name binding annotation To bind filters to your REST endpoints, JAX-RS provides the meta-annotation @NameBinding and it can be used as following: @NameBinding @Retention(RUNTIME) @Target({TYPE, METHOD}) public @interface … Read more
The problem with putting it in the URL is that the URL is supposed to represent a resource by location. An API Version is not a location and it not part of the identifier of the resource. Sticking /v2/ in the URL breaks all existing links that came before. There is one correct way to … Read more
One nice value-add feature of Jersey is the Jersey Test Framework which lets you run and test your Jersey REST services inside JUnit, without the need to first deploy them to a stand-alone server and even before you commit your code to your repo. These tests are easy to write, you can run them before … Read more

Has support for Spring and standard injection containers (ie @Inject). Glassfish bundles it. Its much more modular than the other JAX-RS projects. It has a kick ass URI Builder Does not … Read more
If I understand you correctly, you want to compose a multipart request manually from an HTTP/REST console. The multipart format is simple; a brief introduction can be found in the HTML 4.01 spec. You need to come up with a boundary, which is a string not found in the content, let’s say HereGoes. You set … Read more
The problem is the JSON – this cannot, by default, be deserialized into a Collection because it’s not actually a JSON Array – that would look like this: [ { “name”: “Test order1”, “detail”: “ahk ks” }, { “name”: “Test order2”, “detail”: “Fisteku” } ] Since you’re not controlling the exact process of deserialization (RestEasy … Read more
I was never able to get this to work simple using annotations. To get it to work, I created a ContextResolver for ObjectMapper, then I added the JSR310Module (update: now it is JavaTimeModule instead), along with one more caveat, which was the need to set write-date-as-timestamp to false. See more at the documentation for the … Read more
