L'injection @EJB avec Arquillian sur WebLogic 10.3.5 ne fonctionne pas

Question

J'utilise Arquillian pour lancer un test unitaire de base sur WebLogic 10.3.5. Malheureusement, l'injection @EJB ne fonctionne pas pour moi et obtient une exception NullPointerException lorsque l'EJB est appelé.

Les exemples que j'ai trouvés ne nécessitent pas l'ajout d'un ejb-jar.xml, mais j'en ai ajouté un. Dans tous les cas, une exception NullPointerException est levée.

Des idées?

Le test unitaire:

import static org.testng.Assert.assertEquals; 
import java.io.File; 
import javax.ejb.EJB; 
import org.jboss.arquillian.container.test.api.Deployment; 
import org.jboss.arquillian.testng.Arquillian; 
import org.jboss.shrinkwrap.api.ShrinkWrap; 
import org.jboss.shrinkwrap.api.exporter.ZipExporter; 
import org.jboss.shrinkwrap.api.spec.JavaArchive; 
import org.testng.annotations.Test; 
import eu.ema.eudract.results.DummyService; 
import eu.ema.eudract.results.DummyServiceBean; 

public class ResultStatefulServiceBeanIntegrationTest extends Arquillian { 

    @Deployment 
    public static JavaArchive createDeployment() { 
     JavaArchive archive = ShrinkWrap.create(JavaArchive.class, "test.jar") 
       .addClasses(DummyService.class, DummyServiceBean.class) 
       .addAsManifestResource("META-INF/ejb-jar.xml", "ejb-jar.xml"); 

     System.out.println(archive.toString(true)); 
     archive.as(ZipExporter.class).exportTo(new File("C:\\Users\\fragkakm\\Desktop\\test.jar"), true); 
     return archive; 
    } 

    @EJB 
    private DummyService dummyService; 

    @Test 
    public void loadResultTest() { 
     assertEquals(dummyService.doNothing(), "Did nothing!"); 
    } 
} 

La sortie:

test.jar: 
/META-INF/ 
/META-INF/ejb-jar.xml 
/eu/ 
/eu/ema/ 
/eu/ema/eudract/ 
/eu/ema/eudract/results/

Mon interface EJB:

package eu.ema.eudract.results; 

import javax.ejb.Remote; 

@Remote 
public interface DummyService { 

    String doNothing(); 
} 

L'implémentation EJB:

package eu.ema.eudract.results; 

import javax.ejb.Stateless; 

import eu.ema.eudract.results.DummyService; 

@Stateless 
public class DummyServiceBean implements DummyService { 

    public String doNothing() { 
     return "Did nothing!"; 
    } 

} 

Le arquillian.xml

<?xml version="1.0"?> 
<arquillian xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns="http://jboss.org/schema/arquillian" 
    xsi:schemaLocation="http://jboss.org/schema/arquillian http://jboss.org/schema/arquillian/arquillian_1_0.xsd"> 

    <container qualifier="arquillian-wls-remote-10.3" default="true">

      <property name="target">AdminServer</property> 
     </configuration> 
    </container> 

</arquillian>

Answer 1

WLS 10.3.5 est un conteneur conforme à JEE5, de sorte que vous ne pouvez pas avoir un résident EJB dans un module Web (qui est supporté depuis JEE6 ie WLS 12c).

Pour autoriser l'injection d'EJB dans votre classe de test dans WLS 10.3.x, vous devez fournir les entrées ejb-local-ref associées dans votre fichier web.xml de votre ShrinkWrap WebArchive. Si vous préparez une archive EAR, vous devrez ajouter ces entrées dans le WebArchive qui serait enrichi avec le Testrunner Servlet Arquillian.

Un exemple de ceci est disponible dans la classe de dépôt Arquillian GitHub in the WebLogicInjectionTestCase. Le fichier web.xml associé est in-container-web-eartest.xml.

Notez que les entrées ejb-local-ref sont définitivement requises lorsque vous tentez d'injecter des EJB locaux, puisque WLS ne les lie pas dans l'arborescence JNDI, par défaut. Vous pourriez être en mesure d'ignorer cette condition préalable pour les EJB distants.
