这是我的SLSB:

@Stateless
public class MyService {
  PersistenceContext(unitName = "abc")
  EntityManager em;
  public boolean exists(int id) {
    return this.em.find(Employee.class, id) != null;
  }
}

这是我的persistence.xml(我正在使用Glassfish v3):

<persistence>
  <persistence-unit name="abc">
    <provider>org.hibernate.ejb.HibernatePersistence</provider>
    <jta-data-source>java:/MyDS</jta-data-source>
    <properties>
        <property name="hibernate.archive.autodetection" value="class" />
        <property name="hibernate.dialect"
          value="org.hibernate.dialect.MySQLInnoDBDialect" />
    </properties>
  </persistence-unit>
</persistence>

现在我正在尝试使用OpenEJB嵌入式容器创建测试.这是我的测试类:

class MyServiceText {
  @Test
  public void testChecksExistence() throws Exception {
    Properties properties = new Properties();
    properties.setProperty(
        javax.naming.Context.INITIAL_CONTEXT_FACTORY,
        "org.apache.openejb.client.LocalInitialContextFactory"
    );
    InitialContext ic = new InitialContext(properties);
    // actual testing skipped
  }
}

我想用HSQL进行测试.如何指示OpenEJB我的持久性单元"abc"在测试期间必须指向HSQL？我要创建一个新版本persistence.xml吗？我要用 …
