Jersey 2 in GlassFish 4 - First Java EE 7 Implementation Now Integrated (TOTD #182)

Guest Author

The JAX-RS 2.0 specification released their href="http://jcp.org/aboutJava/communityprocess/edr/jsr339/index3.html">Early
Draft 3 recently. One of my href="https://blogs.oracle.com/arungupta/entry/jax_rs_2_0_early">earlier
blogs explained as the features were first introduced in the
very first draft of the JAX-RS 2.0 specification. Last week was
another milestone when the first Java EE 7 specification
implementation was added to GlassFish 4 builds.

Jakub href="https://blogs.oracle.com/japod/entry/jersey_2_0_integrated_into">blogged
about Jersey 2 integration in GlassFish 4 builds. Most of the basic
functionality is working but EJB, CDI, and Validation are still a
TBD. Here is a simple Tip style="font-weight: bold;">Of The Day
(TOTD) sample to get you started with using that functionality.

  1. Create a Java EE 6-style Maven project

    mvn archetype:generate
    -DarchetypeArtifactId=webapp-javaee6 -DgroupId=example
    -DartifactId=jersey2-helloworld -DarchetypeVersion=1.5

    Note, this is still a Java EE 6 archetype, at least for now.

  2. Open the project in NetBeans IDE as it makes it much easier to
    edit/add the files. Add the following <repositories>

    <name>Java.net Snapshot Repository for Maven</name>

  3. Add the following <dependency>s


    The complete list of Maven coordinates for Jersey2 are href="http://search.maven.org/#search%7Cga%7C1%7Corg.glassfish.jersey">available
    here. An up-to-date status of Jersey 2 can always be
    obtained from

  4. Here is a simple resource class:

    public class MoviesResource {

    public List<Movie> getMovies() {
    List<Movie> movies = new ArrayList<Movie>();

    movies.add(new Movie("Million Dollar Baby", "Hillary Swank"));
    movies.add(new Movie("Toy Story", "Buzz Light Year"));
    movies.add(new Movie("Hunger Games", "Jennifer Lawrence"));

    return movies;

    This resource publishes a list of movies and is accessible at
    "movies/list" path with HTTP GET. The project is using the
    standard JAX-RS APIs.

    Of course, you need the trivial "Movie" and the "Application"
    class as well. They are available in the href="//cdn.app.compendium.com/uploads/user/e7c690e8-6ff9-102a-ac6d-e4aebca50425/f4a5b21d-66fa-4885-92bf-c4e81c06d916/File/536181782352701534846a24f6d0a9f0/totd182_jersey2_helloworld.zip">downloadable
    project anyway.
  5. Build the project

    mvn package

    And deploy to href="http://dlc.sun.com.edgesuite.net/glassfish/4.0/promoted/glassfish-4.0-b43.zip">GlassFish
    4.0 promoted build 43 (download, unzip, and start as
    "bin/asadmin start-domain") as

    asadmin deploy --force=true target/jersey2-helloworld.war

  6. Add a simple test case by right-clicking on the MoviesResource
    class, select "Tools", "Create Tests", and take defaults.
    Replace the function "testGetMovies" to
    public void testGetMovies() {
    Client client = ClientFactory.newClient();
    List<Movie> movieList = client.target("http://localhost:8080/jersey2-helloworld/webresources/movies/list")
    .get(new GenericType<List<Movie>>() {});
    assertEquals(3, movieList.size());

    This test uses the newly defined JAX-RS 2 client APIs to access
    the RESTful resource.

  7. Run the test by giving the command "mvn test" and see the
    output as

    T E S T S
    Running example.MoviesResourceTest
    Tests run: 1, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.561 sec

    Results :

    Tests run: 1, Failures: 0, Errors: 0, Skipped: 0

GlassFish 4 contains Jersey 2 as the JAX-RS implementation. If
you want to use Jersey 1.1 functionality, then href="http://blog.alutam.com/2012/06/26/writing-web-applications-that-can-run-with-jersey-1-x-as-well-as-jersey-2-0/">Martin's
blog provide more details on that. All JAX-RS 1.x
functionality will be supported using standard APIs anyway. This
workaround is only required if Jersey 1.x functionality needs to
be accessed.

    Hi Arun, there's a typo in step 2 "respositories".
