Missing dependencies for HttpServletRequest with Jersey

Question

I have a Standalone Jersey server running at the beginning of my JunitTest. I'm testing if my JaxRS controller works, as well as my custom HttpClient. Please note that I've always been able to use this JaxRsResourceController embedded in glassfish.

Here is the JaxRsController (light version)

@Path("root")
public class JaxRsResourceController implements
        ResourceController<HttpServletRequest> {

    @Context
    private UriInfo context;
    @Context
    HttpServletRequest request;
    @Context
    HttpServletResponse response;

    @GET
    public String hello(){
        System.out.println("Uri is "+this.context.getBaseUri().toString());
        return "Hello "+peoples;
    }

}

I have no problem with the client, but when I start the server, I have :

GRAVE: The following errors and warnings have been detected with resource and/or provider classes:
  SEVERE: Missing dependency for field: javax.servlet.http.HttpServletRequest com.robustaweb.library.rest.controller.implementation.JaxRsResourceController.request
  SEVERE: Missing dependency for field: javax.servlet.http.HttpServletResponse com.robustaweb.library.rest.controller.implementation.JaxRsResourceController.response

    at com.sun.jersey.api.container.httpserver.HttpServerFactory.create(HttpServerFactory.java:172)
    at com.robustaweb.library.rest.server.JerseyServer.startServer(JerseyServer.java:44)

Basically it says that at the @Context injection time, there is no dependency on the HttpServletRequest. However if I remove the @Context annotations on request and response, but keep it for UriInfo context, it's ok, and I can read the Uri.

I changed a few times the Maven pom wich is now to force the libs in:

<dependencies>
    <dependency>
        <groupId>com.sun.jersey</groupId>
        <artifactId>jersey-server</artifactId>
        <version>1.14</version>
    </dependency>
    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>servlet-api</artifactId>
        <version>2.5</version>
    </dependency>
    <dependency>
        <groupId>javax.ws.rs</groupId>
        <artifactId>jsr311-api</artifactId>
        <version>1.1.1</version>
    </dependency>
    <dependency>
        <groupId>javax.servlet.jsp</groupId>
        <artifactId>jsp-api</artifactId>
        <version>2.1</version>
    </dependency>
 </dependencies>

Any idea ?

Answer 1

servlet dependencies were separated to another module, try adding

<dependency>
    <groupId>com.sun.jersey</groupId>
    <artifactId>jersey-servlet</artifactId>
    <version>1.14</version>
</dependency>

to your pom.

Answer 2

It was not easy, but I found out. The thing is that in my JUnit test, I was creating the server like this :

HttpServer server = HttpServerFactory.create(url);

But that way, you create a lightweight container that does not have servlet containers, and so is the failure reason. So in order to have it all, I used the jersey-test-framework that allow to use the Grizzly web container (or even Embedded glassfish).

Here is the maven :

<dependencies>
    <dependency>
        <groupId>javax.ws.rs</groupId>
        <artifactId>jsr311-api</artifactId>
        <version>1.1.1</version>
    </dependency>
    <!-- Unit test are using jersey server directly -->        
    <dependency>
        <groupId>junit</groupId>
        <artifactId>junit</artifactId>
        <version>4.8.1</version>
        <scope>test</scope>
    </dependency>        
    <dependency>
        <groupId>com.sun.jersey.test.framework</groupId>
        <artifactId>jersey-test-framework</artifactId>
        <version>1.0.3</version>
        <scope>test</scope>
    </dependency>    
</dependencies>

Here is the JerseyServerTest : note that it extends JerseyTest

public class JerseyServerTest extends JerseyTest {

    protected String baseUri = "http://localhost:" + TestConstants.JERSEY_HTTP_PORT + "/";

    public JerseyServerTest() throws Exception {
        super("com.robustaweb.library.rest.controller");

        /*
        It's possible to NOT call the super() but to manually do :
        1)  ApplicationDescriptor appDescriptor = new ApplicationDescriptor()
                .setRootResourcePackageName(resourcePackageName) // resource packages
                .setContextPath(contextPath) //context of app
                .setServletPath(servletPath); // context of spi servlet
        2)setupTestEnvironment(appDescriptor);
         */
    }

    @Test
    public void testHelloWorldRequest() {
        SunRestClient client = new SunRestClient(baseUri + "root");
        String result = client.GET("", null);
        System.out.println(result);
    }

    @Test
    public void testDeleteRequest() {
        SunRestClient client = new SunRestClient(baseUri + "root");
        String result = client.DELETE("john", null);
        System.out.println(result);
    }
}

And finally the Resource file, that contains @GET and @DELETE

@Path("root")
public class JaxRsController extends JaxRsResourceController{

    List<String> peoples = new ArrayList<String>();

    @GET
    public String hello(){
        System.out.println("Uri is "+getUri());
        return "Hello "+peoples;
    }   

    @DELETE
    @Path("{name}")
    public String deletePeople(@PathParam("name") String name){
        System.out.println("deleting "+name);
        this.peoples.remove(name);
        return String.valueOf(peoples.size());
    }
}

And now it works ! I had some help in this article, and there is a small chapter on the documentation. Beeing able to attach the source code of the Jersey framework really helped, so thantks to IntelliJ also.
