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:
test.jar:

/eu/ema/eudract/
/eu/ema/eudract/results/

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-refentries in your web.xml of your ShrinkWrapWebArchive. If you prepare an EAR archive, then you’ll need to add these entries into theWebArchivethat 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.
