如果另一个 GF 实例正在运行，EJBContainer.createEJBContainer() 会失败

Question

我有一个运行 TestNG 测试的 Maven 项目，该测试启动 EJBContainer.createEJBContainer()，并且仅当我运行另一个 GF 3.1 时才会失败并出现以下错误。

javax.ejb.EJBException: No EJBContainer provider available
The following providers:
org.glassfish.ejb.embedded.EJBContainerProviderImpl
Returned null from createEJBContainer call.
    at javax.ejb.embeddable.EJBContainer.reportError(EJBContainer.java:216)
    at javax.ejb.embeddable.EJBContainer.createEJBContainer(EJBContainer.java:146)

日志输出指示由以下原因引起：javax.naming.NameNotFoundException：jdbc

FINE: Exception while invoking class org.glassfish.persistence.jpa.JPADeployer prepare method

如果我关闭正在运行的 GF 实例，则 EJBContainer 将启动并正确执行测试。我们使用 Jenkins (Hudson) 进行 CI，它在 GF 中运行，但构建失败。这也会导致本地开发出现问题，因为我必须停止 GF 来运行测试。

我从干净的 GF 安装中复制了domain.xml，更改了所有端口（以避免与正在运行的 GF 实例发生冲突）并将其放置在 ./src/test/resources/org/glassfish/embed/ 。

以下是我创建 EBJContainer 的方法。

    Map<String, Object> properties = new HashMap<String, Object>();
    properties.put(EJBContainer.MODULES, new File[]{new File("target/classes"), new File("target/test-classes")});
    ejbContainer = EJBContainer.createEJBContainer(properties);
    ctx = ejbContainer.getContext();

Maven 依赖。

    <dependency>
        <groupId>org.glassfish.extras</groupId>
        <artifactId>glassfish-embedded-all</artifactId>
        <version>3.1</version>
        <scope>test</scope>
    </dependency>

我觉得我错过了一些简单的东西。提前致谢。

当我开始使用嵌入式 EJB 容器时，我发现的所有参考文献都提到使用预安装的 GF 或从已安装的 GF 实例复制 domain.xml（这就是我所做的）。后来我偶然发现 http://embedded-glassfish.java.net/domain.xml我不再有这个问题了。
