Question

这是我第一次使用OpenEJB容器系统。当我使用InitialContext的lockup-Method时，我得到一个NameNotFoundException。我已经阅读了很多示例和教程，在每个示例中，查找方法都是这样的：

initialContext.lookup("NameOfBean");

现在我找到了另一个使用查找的解决方案，就像下面的代码片段一样，也适用于我。

initialContext.lookup("java:global/classpath.ear/ProjectName/NameofBean");

问题是为什么第一个版本对我不起作用以及我做错了什么？

这是我的TestClass：

public class NamerOfBeanOpenEJBTest {

private static InitialContext initialContext;

@BeforeClass
public static void setUp() throws Exception {
       Properties properties = new Properties();
       properties.setProperty(Context.INITIAL_CONTEXT_FACTORY, "org.apache.openejb.client.LocalInitialContextFactory");
       properties.setProperty("openejb.deployments.classpath.include", ".*");
               initialContext = new InitialContext(properties);
}
@Test
public void testBean() throws NamingException{  
    Object object = initialContext.lookup("java:global/classpath.ear/ProjectName/NameOfBean");
    assertNotNull(object);
    assertTrue(object instanceof NameOfBean);
}

@AfterClass
public static void afterClass() throws Exception {
    if (initialContext != null) {
        initialContext.close();
    }}
}

有人为我提供tipps或解决方案吗？非常感谢。

修改

在JBoss AS 7.1中，查找可以像这样放置：

new InitialContext().lookup("ejb:/ProjectName//NameOfBean!de." + "mypath.sessionbean.stateless.NameOfBeanInterface");

在OpenEJB中是否可能？我是否必须更改每个bean中的每个查找调用以使用OpenEJB进行本地测试？这不会真正有效且节省时间。

问题解决了！

查找的结构是{deploymentId} {interfaceType.annotationName}。因此在我的情况下它必须是

initialContext.lookup("NameOfBeanLocal");

或 initialContext.lookup（ “NameOfBeanRemote”）; 取决于界面的类型。

要解决JBoss问题，您可以从默认查找切换

new InitialContext().lookup("ejb:/ProjectName//NameOfBean!de." + "mypath.sessionbean.stateless.NameOfBeanInterface");

更灵活的东西，如Dependcy-Lookup或Dependency-Injection，并使用@EJB注释。两种方式都是JBoss和OpenEJB的支持。
