如何使用jndi在野蝇中查找本地bean

Question

我的问题似乎与在战争中部署的本地EJB的WildFly JNDI查找相同，只是我无法让他的解决方案工作。

我对部署在jar jaws-server-ejb3中的EJB有一个耳朵。在我的应用程序中，我想在bean上调用一个方法。我已经在我的bean上尝试了有和没有@LocalBean。

野蝇（8.2）启动时打印出来：

java:global/jaws/jaws-server-ejb3/ForecastService!com.termalabs.common.service.ForecastServiceRemote
java:app/jaws-server-ejb3/ForecastService!com.termalabs.common.service.ForecastServiceRemote
java:module/ForecastService!com.termalabs.common.service.ForecastServiceRemote
java:jboss/exported/jaws/jaws-server-ejb3/ForecastService!com.termalabs.common.service.ForecastServiceRemote
java:global/jaws/jaws-server-ejb3/ForecastService
java:app/jaws-server-ejb3/ForecastService
java:module/ForecastService

当我将@LocalBean添加到我的bean中时，我看到：

java:global/jaws/jaws-server-ejb3/ForecastService!com.termalabs.server.service.ForecastService
java:app/jaws-server-ejb3/ForecastService!com.termalabs.server.service.ForecastService
java:module/ForecastService!com.termalabs.server.service.ForecastService
java:global/jaws/jaws-server-ejb3/ForecastService!com.termalabs.common.service.ForecastServiceRemote
java:app/jaws-server-ejb3/ForecastService!com.termalabs.common.service.ForecastServiceRemote
java:module/ForecastService!com.termalabs.common.service.ForecastServiceRemote
java:jboss/exported/jaws/jaws-server-ejb3/ForecastService!com.termalabs.common.service.ForecastServiceRemote

因此，从我读到的所有内容来看，似乎很清楚，我应该能够用“java:app/jaws-server-ejb3/ForecastService”或“java:app/jaws-server-ejb3/ForecastService！com.termalabs.common.service.ForecastServiceRemote”来查找这个bean

以下是我目前硬编码的查找：

public static Object getBeanInternal(String beanName, Class remoteClass) throws NamingException {
    System.out.println("Getting internal bean: " + beanName + " for class "  + remoteClass.getName());
    final Hashtable jndiProperties = new Hashtable();
    jndiProperties.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");
    InitialContext ctx = new InitialContext(jndiProperties);
    Object ejb = ctx.lookup("java:app/jaws-server-ejb3/ForecastService");
//    Object ejb = ctx.lookup("java:global/jaws-server-ejb3/ForecastService!com.termalabs.common.service.ForecastService");
    return ejb;
}

我曾在一个空的JNDiproperty表中尝试过，或者在上面引用的设置中尝试过。无论我做了什么尝试，我最终都会遇到一个巨大的例外，比如

2015-04-07 15:50:01,836 WARN  [com.termalabs.server.system.AutosysJammerSequence] (JammerManager-2015/04/07 15:49:46.710 MDT-0) Can't lookup: javax.naming.NameNotFoundException: java:app/jaws-server-ejb3/ForecastService

    at java.lang.Thread.run(Thread.java:745) [rt.jar:1.8.0_25]

我可以使用远程接口访问这个bean，但是这似乎不对，因为我正在从同一个耳朵运行这个代码。我不需要这样做。

我错过了什么？

谢谢，

迈克尔

查看消息，我看到JammerManager-2015/04/07 15:49:46.710 MDT-0，看起来您正在启动自己的线程。如果您没有使用新的EE并发实用程序，那么命名上下文很可能没有复制到线程中。您需要确保为新线程设置了命名上下文、安全上下文和TCCL。
