JBAS011440: Can't find a persistence unit named null in deployment "test.war"

[david.salter]

Hi,

I'm attempting to write an Arquillian test to test some JPA queries on AS 7.1.1

My test class is basically:

@RunWith(Arquillian.class)
public class ManagerBeanTest {


  @Deployment
  public static Archive<?> createDeployment() {
  return ShrinkWrap.create(WebArchive.class, "test.war")
  .addPackage(ManagerBean.class.getPackage())
  .addPackage(MyEntity.class.getPackage())
  .addAsManifestResource("META-INF/test-persistence.xml", "persistence.xml")
  .addAsWebResource(EmptyAsset.INSTANCE, "beans.xml");
  }

  @PersistenceContext
  EntityManager em;


  @Test
  public void myTest() {
  ...
  }
}

When I run the test however, JBoss gives me an error:

Caused by: org.jboss.as.server.deployment.DeploymentUnitProcessingException: JBAS011047: Component class xxx.ManagerBean for component ManagerBean has errors:

JBAS011440: Can't find a persistence unit named null in deployment "test.war"

Can anyone help with what this means?

Thanks,

David.

addAsManifestResource in a WebArchive will place it under /META-INF

Try using addAsResource("META-INF/persistence.xml", "META-INF/persistence.xml") -> /WEB-INF/classes/ + META-INF/persistence.xml

[david.salter]

That works perfectly.  Thanks very much

Hi, David, I have a similar situation, I'll explain it: I have 3 projects

1. Project Web (deployed as a .war)
2. Project EJB (deployed as a .jar)
3. Project JPA v2 (deployed as a .jar too)

The problem appear when I try to connect my EJB v3.1 with my JPA v2.0, this were the steps I followed:

1. All projects were builds successfully in Eclipse Indigo.
2. The JPA project was exported as jar and deployed to JBossAS 7.1.0
3. When I tried to export the EJB project to a jar in JBossAS I receive --> JBAS011440: Can't find a persistence unit named EntityProject in deployment "Manager.jar"

In the EJB project I have used EntityManager like this:

@PersistenceContext(unitName="EntityProject")

private EntityManager em;

In my JPA project I have generated all the classes from an Oracle DB (v11g), this is my persistance.xml:

<?xml version="1.0" encoding="UTF-8"?>

<persistence version="2.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">

    <persistence-unit name="EntityProject">

    <jta-data-source>java:/OracleDS</jta-data-source>

        <class>org.package.X</class>

        <class>org.package.Y</class>

        <class>org.package.Z</class>

        <properties>

            <property name="hibernate.dialect" value="org.hibernate.dialect.OracleDialect"/>

            <property name="hibernate.connection.driver_class" value="oracle.jdbc.driver.OracleDriver"/>

            <property name="hibernate.connection.url" value="jdbc:oracle:thin:@localhost:1521:db"/>

            <property name="hibernate.default_schema" value="user"/>

            <property name="hibernate.connection.username" value="user"/>

            <property name="hibernate.connection.password" value="passw"/>

            <property name="hibernate.show_sql" value="true"/>

        </properties>

    </persistence-unit>

</persistence>

Also, all my projects are independents, they don't belong to any EAR project.

Please, I would appreciate some help,

Sandy...

same issue for me I can't run a Junit Test using Arquillian on Wildfly 8...

this is my test:

@RunWith(Arquillian.class)

public class GenericDaoTest {

    @Inject

    private EmployeeService employeeService;

    @Deployment

    public static JavaArchive createTestableDeployment() {

        final JavaArchive jar = ShrinkWrap

                .create(JavaArchive.class)

                .addPackage("service")

                .addPackage("service.impl")

                .addAsManifestResource("META-INF/persistence.xml",

                        "persistence.xml, test-persistence.xml")

                .addAsManifestResource(EmptyAsset.INSTANCE, "beans.xml")

                .addPackage("entity");

        return jar;

    }

    @Test

    public void should_crud() {

        assertNotNull(employeeService);

        Employee initialSize = employeeService.findById(new Integer(1));

    }

}

Datastore for mysql has been created and test successful

Service classes has writed as below:

@Local

public interface GenericService<T, PK extends Serializable>{

    T findById(PK id);

}

------------------------------------------------------------------------------------------------------------------------------------------------

@Local

public interface EmployeeService extends

        GenericService<Employee,Integer> {

    }

------------------------------------------------------------------------------------------------------------------------------------------------

@Stateless(name = "GenericServiceImpl", mappedName = "GenericServiceImpl")

public class GenericServiceImpl<T, PK extends Serializable> implements

        GenericService<T, PK> {

    @PersistenceContext(unitName = "timesheet")

    protected EntityManager entityManager;

    private Class<T> entityClass;

    public GenericServiceImpl() {

    }

    public GenericServiceImpl(Class<T> entityClass) {

        this.entityClass = entityClass;

    }

    @Override

    public T findById(PK id) {

        return entityManager.find(entityClass, id);

    }

}

------------------------------------------------------------------------------------------------------------------------------------------------

A test-persistence,xml has been created too:

<persistence version="2.1"

   xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

   xsi:schemaLocation="

        http://xmlns.jcp.org/xml/ns/persistence

        http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd">

   <persistence-unit name="primary">

      <jta-data-source>java:jboss/datasources/Timesheet</jta-data-source>

      <properties>

         <!-- Properties for Hibernate -->

         <property name="hibernate.hbm2ddl.auto" value="create-drop" />

         <property name="hibernate.show_sql" value="false" />

      </properties>

   </persistence-unit>

</persistence>

But it doesn't work with this error:

	"WFLYCTL0080: Failed services" => {"jboss.deployment.unit.\"test.war\".INSTALL" => "org.jboss.msc.service.StartException in service jboss.deployment.unit.\"test.war\".INSTALL: WFLYSRV0153: Failed to process phase INSTALL of deployment \"test.war\"
	Caused by: org.jboss.as.server.deployment.DeploymentUnitProcessingException: WFLYEE0041: Component class service.impl.GenericServiceImpl for component EmployeeServiceImpl has errors:

WFLYJPA0033: Can't find a persistence unit named timesheet in deployment \"test.war\""},

	"WFLYCTL0180: Services with missing/unavailable dependencies" => [
	"jboss.deployment.unit.\"test.war\".batch.environment is missing [jboss.deployment.unit.\"test.war\".beanmanager]",
	"jboss.deployment.unit.\"test.war\".weld.weldClassIntrospector is missing [jboss.deployment.unit.\"test.war\".beanmanager]"
	]

}

Thanks a lot

solved creating a test persistence xml importing into my junit test as following:

<persistence version="2.1"

    xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    xsi:schemaLocation="

        http://xmlns.jcp.org/xml/ns/persistence

        http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd">

    <persistence-unit name="PU-NAME">

        <jta-data-source>java:jboss/datasources/MyDatasource</jta-data-source>

        <properties>

            <!-- Properties for Hibernate -->

            <property name="hibernate.show_sql" value="false" />

        </properties>

    </persistence-unit>

</persistence>

and added with .addAsResource method in junit test
