Glassfish上EJB的可移植JNDI语法查找
以前的尝试是让Netbeans将一个EJB模块部署到Netbeans可以访问的Glassfish服务器上，该模块构建为JAR而不是EAR。 但是，使用asadmin通过CLI将JAR部署到Glassfish 可能会遇到错误 。
EAR通过CLI进行部署而没有问题 – 但是，EJB的JNDI名称似乎不起作用。 差异是什么？
32.4.1.1可移植JNDI语法
三个JNDI名称空间用于可移植的JNDI查找：java：global，java：module和java：app。
java：global JNDI名称空间是使用JNDI查找查找远程企业bean的可移植方式。 JNDI地址具有以下forms：java：global [/ application name] / module name / enterprise bean name [/ interface name]应用程序名称和模块名称默认为应用程序和模块的名称减去文件扩展名。 仅当应用程序打包在EAR中时，才需要应用程序名称。 仅当企业bean实现多个业务接口时，才需要接口名称。

查找此bean的正确语法是什么？ 是java:global/HelloEAR/HelloEAR-ejb/greetings.GreetingsBeanRemote ？ 我尝试了不止一些变种而没有成功。

为什么没有“java：”或类似的东西调用bean？

如果您正在使用Maven，那么检查“-1.0-SNAPSHOT”（或其他版本/根据您的应用程序）是否附加在application-ejb文件名末尾为“application-ejb-1.0-SNAPSHOT”，全名是“java：global / application-ear / application-ejb-1.0-SNAPSHOT / fileName”
