Question

我有与WildFly JNDI lookup for local EJB deployed in a war相同的问题，除了我无法让他的解决方案起作用。

我在jar jaws-server-ejb3中部署了EJB。在我的应用程序内部，我想在bean上调用一个方法。我在我的bean上使用和不使用@LocalBean尝试了这个。

当wildfly（8.2）启动时，它打印出来：

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看来，我应该能够使用“java：app / jaws-server-ejb3 / ForecastService”或“java：app / jaws-server-ejb3 / ForecastService！com”查找此bean。 termalabs.common.service.ForecastServiceRemote“

这是我目前硬编码的查询：

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;
}

我尝试使用空的jndiProperties表或上面引用的设置。无论我尝试过什么，我最终都会遇到像

这样的NamingException

    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此bean，但这似乎不对，因为我从同一个耳朵运行此代码。我不应该这样做。

我错过了什么？

谢谢，

查看我看到JammerManager-2015/04/07 15:49:46.710 MDT-0的消息，看起来您正在启动自己的线程。如果您不使用新的EE并发实用程序，则命名上下文可能不会复制到您的线程中。您需要确保为新线程设置命名上下文，安全上下文和TCCL。
