JBOSS JNDI無狀態bean查找字符串

在JBOSS 7.1上使用Eclipse工具部署EJB應用程序
要使用的查找字符串的格式是什麼。JBOSS JNDI無狀態bean查找字符串

我接過一看文檔，但我發現真的很困惑

context.lookup("ejb:" + appName + "/" + moduleName + "/" + distinctName + "/" + beanName + "!" + viewClassName);

你能幫忙嗎？

當EJB部署（例如，當EJB部署到服務器或服務器重新啓動），你應該看到像這樣的輸出：

2015 Jun 07, 18:07:24.352 (MSC service thread 1-4) INFO - (AbstractDeploymentUnitService.java:66) start - JBAS015876: Starting deployment of "_ExampleEjbProject.war" 
2015 Jun 07, 18:07:24.463 (MSC service thread 1-4) INFO - (EjbJndiBindingsDeploymentUnitProcessor.java:182) setupJNDIBindings - JNDI bindings for session bean named SayHelloEjb in deployment unit deployment "_ExampleEjbProject.war" are as follows: 

    java:global/_ExampleEjbProject/SayHelloEjb!org.yaorma.examples.ejb.server.local.SayHelloLocal 
    java:app/_ExampleEjbProject/SayHelloEjb!org.yaorma.examples.ejb.server.local.SayHelloLocal 
    java:module/SayHelloEjb!org.yaorma.examples.ejb.server.local.SayHelloLocal 
    java:global/_ExampleEjbProject/SayHelloEjb!org.yaorma.examples.ejb.server.remote.SayHelloRemote 
    java:app/_ExampleEjbProject/SayHelloEjb!org.yaorma.examples.ejb.server.remote.SayHelloRemote 
    java:module/SayHelloEjb!org.yaorma.examples.ejb.server.remote.SayHelloRemote 
    java:jboss/exported/_ExampleEjbProject/SayHelloEjb!org.yaorma.examples.ejb.server.remote.SayHelloRemote

這是一個字符串列表，可以用於jndi查找字符串的不同上下文中。在這種情況下，我的項目名稱是_ExampleEjbProject，沒有子模塊，bean類（實現）使用這個「@Stateless（name =」SayHelloEjb「）」來註釋以給出ejb名稱，並且本地和遠程接口是「 org.yaorma.examples.ejb.server.local.SayHelloLocal「和」org.yaorma.examples.ejb.server.remote.SayHelloLocal「。查找字符串遵循的模式：

<project_name>/<submodule>/<EJB_name>!<interface_name>.

從一個獨立的應用程序，我能夠用這個字符串來連接：

/_ExampleEjbProject/SayHelloEjb!org.yaorma.examples.ejb.server.remote.SayHelloRemote

像這樣：

public static void main(String[] args) throws Exception { 
     Properties jndiProperties = new Properties(); 
     String providerURL = "remote://localhost:7447"; 
     jndiProperties.put(Context.INITIAL_CONTEXT_FACTORY, org.jboss.naming.remote.client.InitialContextFactory.class.getName()); 
     jndiProperties.put(Context.PROVIDER_URL, providerURL); 
     jndiProperties.put("jboss.naming.client.ejb.context", true); 
     jndiProperties.put(Context.SECURITY_PRINCIPAL, MY_UID); 
     jndiProperties.put(Context.SECURITY_CREDENTIALS, MY_PWD); 
     InitialContext context = new InitialContext(jndiProperties); 
     testLookup(context, "/_ExampleEjbProject/SayHelloEjb!org.yaorma.examples.ejb.server.remote.SayHelloRemote"); 
     System.out.println("Done!"); 
    } 

    private static void testLookup(InitialContext context, String lookupString) throws Exception { 
     Object obj = context.lookup(lookupString); 
     SayHelloRemote sayHelloRemote = (SayHelloRemote) obj; 
     String msg = sayHelloRemote.sayHello("John"); 
     System.out.println(msg); 
    }
