JBOSS EAP6 系列二 客户端访问位于EAR中的EJB时，jndi name要遵守的规则

EJB 的 jndi语法（在整个调用远程ejb的过程中语法的遵循是相当重要的）

参见jboss-as-quickstarts-7.1.1.CR2\ejb-remote\client\src\main\java\org\jboss\as\quickstarts\ejb\remote\client\RemoteEJBClient.java 中的注释：

<span style="font-size:18px;"><span style="font-size:18px;">  // The JNDI lookup name for a stateless session bean has the syntax of:
// ejb:<appName>/<moduleName>/<distinctName>/<beanName>!<viewClassName>

// <appName> The application name is the name of the EAR that the EJB is deployed in
//           (without the .ear).  If the EJB JAR is not deployed in an EAR then this is
//           blank.  The app name can also be specified in the EAR's application.xml
//
// <moduleName> By the default the module name is the name of the EJB JAR file (without the
//              .jar suffix).  The module name might be overridden in the ejb-jar.xml
//
// <distinctName> : AS7 allows each deployment to have an (optional) distinct name.
//                  This example does not use this so leave it blank.
//
// <beanName>     : The name of the session been to be invoked.
//
// <viewClassName>: The fully qualified classname of the remote interface.  Must include
//                  the whole package name.</span></span>

// The JNDI lookup name for a stateful session bean has the syntax of:
// ejb:<appName>/<moduleName>/<distinctName>/<beanName>!<viewClassName>?stateful

<span style="font-size:18px;"><span style="font-size:18px;"> //
// <appName> The application name is the name of the EAR that the EJB is deployed in
//           (without the .ear).  If the EJB JAR is not deployed in an EAR then this is
//           blank.  The app name can also be specified in the EAR's application.xml
//
// <moduleName> By the default the module name is the name of the EJB JAR file (without the
//              .jar suffix).  The module name might be overridden in the ejb-jar.xml
//
// <distinctName> : AS7 allows each deployment to have an (optional) distinct name.
//                  This example does not use this so leave it blank.
//
// <beanName>     : The name of the session been to be invoked.
//
// <viewClassName>: The fully qualified classname of the remote interface.  Must include
//                  the whole package name.</span></span>

现在我们对上面的语法进行细化，这是最容易出错的地方！

1. 纯EJB jar部署中的bean的访问

1.1 JNDI lookup name for astatelesssession bean has the syntax of:

<span style="font-size:18px;"><span style="font-size:18px;"><span style="font-size:18px;">    ejb:/<moduleName>/<distinctName>/<beanName>!<viewClassName>
或者
ejb:/<moduleName>/<distinctName>//<beanName>!<viewClassName>

比如：
"ejb:/jboss-as-ejb-remote-app/CounterBean!" + RemoteCounter.class.getName()
"ejb:/jboss-as-ejb-remote-app//CounterBean!" + RemoteCounter.class.getName()</span></span></span>

1.2 JNDI lookup name for astatefullsession bean has the syntax of:

<span style="font-size:18px;"><span style="font-size:18px;">ejb:/<moduleName>/<distinctName>/<beanName>!<viewClassName>?stateful
或者
ejb:/<moduleName>/<distinctName>//<beanName>!<viewClassName>?stateful

比如：
"ejb:/jboss-as-ejb-remote-app/CounterBean!" + RemoteCounter.class.getName()+"?stateful"
"ejb:/jboss-as-ejb-remote-app//CounterBean!" + RemoteCounter.class.getName()+"?stateful"</span></span>

2. 包含在 ear部署中的EJB jar中的bean的访问

2.1 JNDI lookup name for astatelesssession bean has the

syntax of:

<span style="font-size:18px;"><span style="font-size:18px;">ejb:<appName>/<moduleName>/<distinctName>/<beanName>!<viewClassName>
或者
ejb:<appName>/<moduleName>/<distinctName>//<beanName>!<viewClassName>

比如：
"ejb:nms-server-ear/nms-server-ejb/SecuredRemoteSession!" + ISecuredRemoteSession.class.getName()
"ejb:nms-server-ear/nms-server-ejb//SecuredRemoteSession!" + ISecuredRemoteSession.class.getName()

注意： appName 前面没有 斜线 "/"!!! 这是最容易出错的地方！！！
（如果以斜线开头，表明是ejb jar不是在 ear中部署的！！！）</span></span>

2.2 JNDI lookup name for astatefullsession bean has the syntax of:

<span style="font-size:18px;"><span style="font-size:18px;">ejb:<appName>/<moduleName>/<distinctName>/<beanName>!<viewClassName>?stateful
或者
ejb:<appName>/<moduleName>/<distinctName>//<beanName>!<viewClassName>?stateful

注意： <span style="color:#FF0000;">appName 前面没有 斜线 "/"!!! 这是最容易出错的地方！！！</span>
（如果以斜线开头，表明是ejb jar不是在 ear中部署的！！！）</span></span>

总结

看英文文档耐人寻味啊，好好学习英语吧，外网的资料更加的可靠啊！
