JAX-RS is an specification (just a definition) and Jersey is a JAX-RS implementation.

Jackson + Builder Pattern?
As long as you are using Jackson 2+, then there is now built in support for this. First you need to add this annotation to your Address class: @JsonDeserialize(builder = Address.Builder.class) Then you need to add this annotation to your Builder class: @JsonPOJOBuilder(buildMethodName = “create”, withPrefix = “set”) You can skip this second annotation if … Read more
What is the difference between @PathParam and @QueryParam
Query parameters are added to the URL after the ? mark, while a path parameter is part of the regular URL. In the URL below tom could be the value of a path parameter and there is one query parameter with the name id and value 1: http://mydomain.example/tom?id=1
Dependency injection with Jersey 2.0
You need to define an AbstractBinder and register it in your JAX-RS application. The binder specifies how the dependency injection should create your classes. public class MyApplicationBinder extends AbstractBinder { @Override protected void configure() { bind(MyService.class).to(MyService.class); } } When @Inject is detected on a parameter or field of type MyService.class it is instantiated using the … Read more
Input and Output binary streams using JERSEY?
I managed to get a ZIP file or a PDF file by extending the StreamingOutput object. Here is some sample code: @Path(“PDF-file.pdf/”) @GET @Produces({“application/pdf”}) public StreamingOutput getPDF() throws Exception { return new StreamingOutput() { public void write(OutputStream output) throws IOException, WebApplicationException { try { PDFGenerator generator = new PDFGenerator(getEntity()); generator.generatePDF(output); } catch (Exception e) { … Read more
what’s the correct way to send a file from REST web service to client?
I don’t recommend encoding binary data in base64 and wrapping it in JSON. It will just needlessly increase the size of the response and slow things down. Simply serve your file data using GET and application/octect-streamusing one of the factory methods of javax.ws.rs.core.Response (part of the JAX-RS API, so you’re not locked into Jersey): @GET … Read more
RESTful on Play! framework
As per request, a simple REST-like approach. It works almost the same way Codemwncis’ solution works but uses the Accept header for content negotiation. First the routes file: GET /user/{id} Application.user POST /user/ Application.createUser PUT /user/{id} Application.updateUser DELETE /user/{id} Application.deleteUser You don’t specify any content type here. Doing so is IMHO only necessary when you … Read more
How to access parameters in a RESTful POST method
Your @POST method should be accepting a JSON object instead of a string. Jersey uses JAXB to support marshaling and unmarshaling JSON objects (see the jersey docs for details). Create a class like: @XmlRootElement public class MyJaxBean { @XmlElement public String param1; @XmlElement public String param2; } Then your @POST method would look like the … Read more
What does Provider in JAX-RS mean?
Providers are a simply a way of extending and customizing the JAX-RS runtime. You can think of them as plugins that (potentially) alter the behavior of the runtime, in order to accomplish a set of (program defined) goals. Providers are not the same as resources classes, they exist, conceptually, at a level in-between resources classes … Read more
Difference between JAX-RS and Spring Rest
JAX-RS JAX-RS is a specification for implementing REST web services in Java, currently defined by the JSR-370. It is part of the Java EE technologies, currently defined by the JSR 366. Jersey (shipped with GlassFish and Payara) is the JAX-RS reference implementation, however there are other implementations such as RESTEasy (shipped with JBoss EAP and … Read more
