@EJB injection with Arquillian on WebLogic 10.3.5 doesn't work

Question

I am using Arquillian to run a basic unit test on WebLogic 10.3.5. Unfortunately, @EJB injection does not work for me, and get a NullPointerException when the EJB is invoked.

The examples I found don't require an ejb-jar.xml to be added, but I added one. In any case, a NullPointerException is thrown.

Any ideas?

The unit test:

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!");
    }
}

The output:

My EJB interface:

package eu.ema.eudract.results;

import javax.ejb.Remote;

@Remote
public interface DummyService {

    String doNothing();
}

The EJB implementation:

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!";
    }

}

The 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>

</arquillian>

Answer 1

WLS 10.3.5 is a JEE5 compliant container, so you cannot have an EJB resident in a web-module (which is supported since JEE6 i.e. WLS 12c).

To allow for EJBs to be injected into your test class in WLS 10.3.x, you'll need to provide the associated ejb-local-ref entries in your web.xml of your ShrinkWrap WebArchive. If you prepare an EAR archive, then you'll need to add these entries into the WebArchive that would be enriched with the Arquillian Servlet Testrunner.

An example of this is available in the Arquillian GitHub repository in the WebLogicInjectionTestCase class. The associated web.xml file is in-container-web-eartest.xml.

Note that the ejb-local-ref entries are definitely required when you attempt injection of Local EJBs, since WLS does not bind them in the JNDI tree, by default. You might be able to skip this prerequisite for remote EJBs.
