选定的bean不在同一个模块或企业应用程序中 [英] selected bean is not in the same module or enterprise application
本文介绍了选定的bean不在同一个模块或企业应用程序中的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
在黑暗中只是一个镜头，但是当我尝试通过Netbeans远程调用该bean时，需要一个本地界面来调用远程无状态EJB？
/ p>
Netbeans不允许在此bean上进行远程调用或任何调用。为什么不这样？
尝试手动执行，如下所示：
什么是jndi 全局

信息：RemoteSalutation-ejb已成功部署在941毫秒。
如果可能，我宁愿在属性文件中指定类，而不是硬编码。无论如何，不同的变化导致查找失败。以下是堆栈跟踪：

@Override

请注意，界面是 strong>，即：它实际上是一个Java类库。正确？这使得EJB远程。
引用：
https://netbeans.org/kb/docs/javaee/entappclient.html
尽管我改变了名字，但其实应该和教程一样。
解决方案
尝试 Object o = ic.lookup（salutationBean）;
请注意，mappedName指定要在JNDI中进行远程访问的名称。
Just a shot in the dark, but do I need a local interface to call a remote stateless EJB?
when I try call the bean remotely through Netbeans:
Netbeans doesn't allow a remote call, or any call, on this bean. Why not?
Trying to do it manually, as below:
What is the jndi global remote name for the Remote EJB which is deployed on glassfish?
INFO: visiting unvisited references
INFO: visiting unvisited references
INFO: EJB5181:Portable JNDI names for EJB MyRemoteSessionClass: [java:global/RemoteSalutation-ejb/MyRemoteSessionClass!net.bounceme.dur.glassfish.MyRemoteSession, java:global/RemoteSalutation-ejb/MyRemoteSessionClass]
INFO: RemoteSalutation-ejb was successfully deployed in 941 milliseconds.
If possible, I would rather specify the class in the properties file rather than hard-coded. In any event, different variations result in a lookup failure. Here's the stack-trace:

}
@Override
public String SayBye() {
return "goodbye..";
}
}
note that the interface is remote, ie: it's literally a Java class library. Correct? This makes the EJB remote.
referencing:
https://netbeans.org/kb/docs/javaee/entappclient.html
although I changed the names a bit..otherwise should be exactly as the tutorial.
解决方案
Try Object o = ic.lookup("salutationBean");
Note that mappedName specifies the name to use in JNDI for a remote access.
