在Glassfish上針對EJB的可移植JNDI語法查找

Question

先前的嘗試是讓Netbeans將EJB模塊 （它以JAR而不是EAR的形式） 部署到Netbeans可以訪問的Glassfish服務器上。 但是，使用asadmin通過CLI將JAR部署到Glassfish 可能會遇到bug 。

EAR可以通過CLI毫無問題地進行部署-但是，EJB的JNDI名稱似乎不起作用。 什么是差異？

32.4.1.1可移植JNDI語法

三種JNDI名稱空間用於可移植JNDI查找：java：global，java：module和java：app。

java：global JNDI命名空間是使用JNDI查找查找遠程企業bean的可移植方式。 JNDI地址的格式如下：java：global [/應用程序名稱] /模塊名稱/企業bean名稱[/接口名稱]應用程序名稱和模塊名稱默認為應用程序和模塊的名稱減去文件擴展名。 僅當應用程序打包在EAR中時，才需要應用程序名稱。 僅當企業bean實現多個業務接口時，才需要接口名稱。

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

查找此bean的正確語法是什么？ 是java:global/HelloEAR/HelloEAR-ejb/greetings.GreetingsBeanRemote嗎？ 我已經嘗試了多個不成功的變體。

為什么在沒有“ java：”之類的情況下調用bean？

如果您也使用Maven，請檢查在application-ejb文件名的末尾是否附加了“ -1.0-SNAPSHOT”（或其他版本/根據您的應用程序），名稱是否為“ application-ejb-1.0-SNAPSHOT”，全名將為“ java：global / application-ear / application-ejb-1.0-SNAPSHOT / fileName”
