在玻璃鱼上可移植的EJB JNDI语法查找

Question

Previous attempts were to have Netbeans deploy an EJB module作为一个JAR而不是EAR构建到Netbeans可以访问的Glassfish服务器上。但是，使用asadmin possibly runs into a bug通过CLI将该JAR部署到Glassfish。

EAR通过CLI进行部署，没有问题--但是，EJB的JNDI名称似乎不起作用。有什么不一致？

32.4.1.1便携式JNDI语法 三个JNDI名称空间用于可移植的JNDI查找:java:全局、java:模块和java:app。 java:全局JNDI命名空间是使用JNDI查找查找远程企业bean的可移植方式。JNDI地址的形式如下:java:全局/应用程序名称/模块名、/enterprise bean名称/接口名称、应用程序名称和模块名，默认为应用程序名称，模块名减去文件扩展名。只有当应用程序被打包在EAR中时，才需要应用程序名称。只有当企业bean实现多个业务接口时，才需要接口名称。

http://docs.oracle.com/javaee/7/tutorial/doc/ejb-intro004.htm

查找这个bean的正确语法是什么？是java:global/HelloEAR/HelloEAR-ejb/greetings.GreetingsBeanRemote吗？我试过不止几种变体，但都没有成功。

如果您也在使用Maven，然后检查“-1.0-快照”(或其他版本/根据您的应用程序)是否附加在应用程序的末尾-ejb文件名为“application-ejb -1.0-快照”，全名为"java:global/application-ear/application-ejb-1.0-SNAPSHOT/fileName“。
