HSQLDB EJB3.0 Hibernate无法连接到数据库
我正在尝试创建一个EJB3.0容器管理的持久性bean,但在连接到单元测试使用的内存中HSQLDB时遇到问题。我将OpenEJB用于我的独立容器实现 我的持久性XML中有以下内容HSQLDB EJB3.0 Hibernate无法连接到数据库,hibernate,ejb,hsqldb,persistence.xml,Hibernate,Ejb,Hsqldb,Persistence.xml,我正在尝试创建一个EJB3.0容器管理的持久性bean,但在连接到单元测试使用的内存中HSQLDB时遇到问题。我将OpenEJB用于我的独立容器实现 我的持久性XML中有以下内容 <persistence-unit name="wyvern-unit-test"> <description>In-memory HSQLDB database persistence unit used for unit testing.</description>

这是我的单元测试:
public class LogEntryServiceBeanTest {
private static Context context;
@BeforeClass
public static void beforeClass() {
context = EJBContainer.createEJBContainer().getContext();
}
@AfterClass
public static void afterClass() throws NamingException {
context.close();
}
@Test
public void createLogEntryTest() throws NamingException {
LogEntryService logEntryService = (LogEntryService) context.lookup("java:global/classes/LogEntryServiceBean");
LogEntry logEntry = new LogEntry();
Addressee addressee = new Addressee();
logEntry.setSummary("This is a log entry.");
addressee.setName("John Smith");
addressee.setEmailAddress("john.smith@acme.com.au");
logEntry.getAddressees().add(addressee);
logEntryService.save(logEntry);
}
}
当我运行单元测试时,出现以下错误:
java.sql.SQLException:分配连接时出错。原因:无法分配连接,因为:java.net.ConnectException:连接到端口1527上的服务器本地主机时出错,消息连接被拒绝
关于我做错了什么(或根本没有做)有什么想法吗
谢谢,我是个白痴。我正在启动EJB3.0嵌入式容器,它在VM OpenEJB嵌入式容器中使用GlassFish库 即:
@BeforeClass
public static void beforeClass() {
context = EJBContainer.createEJBContainer().getContext();
}
应该是:
@BeforeClass
public static void beforeClass() {
Properties properties = new Properties();
properties.setProperty(Context.INITIAL_CONTEXT_FACTORY, "org.apache.openejb.client.LocalInitialContextFactory");
context = new InitialContext(properties);
}
此外,由于HSQLDB是一个非JTA数据源,我需要指定persistence.xml持久化单元,如下所示:
<persistence-unit name="wyvern-unit" transaction-type="RESOURCE_LOCAL">
