使用EJBContainer对我的JUnit测试进行java.lang.NullPointerException

我正在进行JUnit测试，并且我的堆栈跟踪中出现了一些我无法理解的错误。我也不确定我用于OpenEJB和Hibernate的版本。

我的JUnit：

public class UsersDaoTest {
@EJB
private UsersDao usersDao;

@Test
public void testPersist() {
    UsersBean usersBean = TrialUtil.generateUser(usersDao, "one", "john", "password", "john", "smith", "james");
    assertNotNull(usersBean);
}

@Test
public void testIsUserRegistered() {
    TrialUtil.generateUser(usersDao, "one", "john", "password", "john", "smith", "james");
    assertNotNull(usersDao.isUserRegistered("john", "password"));
}

private static EJBContainer container;

@BeforeClass
public static void start() {
    container = TrialUtil.createContainer();
}

@Before
public void inject() throws NamingException {
    container.getContext().bind("inject", this);
}

@AfterClass
public static void stop() {
    container.close();
} }

虽然这是我的TrialUtil类：

public class TrialtUtil {

public static UsersBean generateUser(UsersDao usersDao,
        String userId, String username, String password, String firstName,
        String lastName, String middleName) {
    UsersBean usersBean = new UsersBean();
    usersBean .setUserId(userId);
    usersBean .setUsername(username);
    usersBean .setPassword(password);
    usersBean .setFirstName(firstName);
    usersBean .setLastName(lastName);
    usersBean .setMiddleName(middleName);
    usersDao .makePersistent(usersBean);
    return usersBean;
}

public static EJBContainer createContainer() {
    // TODO Auto-generated method stub
    final Properties p = new Properties();

    // HSQL
    p.put("SampleDataSource", "new://Resource?type=DataSource");
    p.put("SampleDataSource.JdbcDriver", "org.hsqldb.jdbcDriver");
    p.put("SampleDataSource.JdbcUrl", "jdbc:hsqldb:mem:mem:aname");
    p.put("SampleDataSource.UserName", "sa");

    return EJBContainer.createEJBContainer(p);
} }

的persistence.xml：

<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="SampleApiPersistenceUnit" transaction-type="JTA">
    <provider>org.hibernate.ejb.HibernatePersistence</provider>
    <jta-data-source>SampleDataSource</jta-data-source>
    <class>com.test.rest.sample.entity.testdb.MstMusicBean</class>
    <properties>
        <property name="hibernate.dialect" value="org.hibernate.dialect.HSQLDialect" />
        <property name="hibernate.hbm2ddl.auto" value="create" />
    </properties>
</persistence-unit>

所以这是我的堆栈跟踪（抱歉，我无法正确格式化。）：

因此NullPointerException指向container.close();行的TrialUtil类。我已经阅读了this和this，但我不太确定我在Eclipse（JavaEE）中使用的是什么版本。如果有人知道这些错误，请帮忙。谢谢。
