Jboss 7.1 Ejb3 Struts2和EAR无法使用JNDI执行EJB

Question

我是EJB和JBoss世界的新手，在尝试通过远程接口执行无状态bean时遇到了问题。

我在Struts ActionSupport的这样做：

public String inscrire() { 
    System.out.println("########### Inscrire Action #############"); 
    Candidat c = new Candidat(nom, prenom, mail, telephone, ecole); 
    try { 
     final Properties env = new Properties(); 
     env.put(Context.INITIAL_CONTEXT_FACTORY, 
       org.jboss.naming.remote.client.InitialContextFactory.class 
         .getName()); 
     env.put(Context.PROVIDER_URL, "remote://localhost:4447"); 
     env.put(Context.SECURITY_PRINCIPAL, "UserApp"); 
     //env.put("jboss.naming.client.ejb.context", "true"); 
     env.put(Context.SECURITY_CREDENTIALS, "password"); 
     InitialContext remoteContext = new InitialContext(env); 
     System.out.println("########## Initial Context OK ##########"); 

     servicecandidat = (CandidatSessionRemote) remoteContext 
       .lookup("java:global/EtestEAProject/EtestMetier/CandidatSession!sessions.candidat.CandidatSessionRemote"); 
     System.out.println("########## LookUp OK ##########"); 

     if (servicecandidat.inscrireCandidat(c)) 
      return SUCCESS; 
     else 
      return ERROR; 
    }catch (Exception lookupError) { 
     System.out.println("########## LookUp EcheC##########"); 
     lookupError.printStackTrace(); 
     return ERROR; 
    } 

控制台使试图执行梅索德

15:01:45,474 INFO [stdout] (http-localhost-127.0.0.1-8080-1) ########## Initial Context OK ########## 

15:01:45,680 INFO [stdout] (http-localhost-127.0.0.1-8080-1) ########## LookUp ExcheC##########

........................... 

和EJB JAR部署时，如下因素命名exeption说：

java:global/EtestEAProject/EtestMetier/CandidatSession!sessions.candidat.CandidatSessionRemote 

    java:app/EtestMetier/CandidatSession!sessions.candidat.CandidatSessionRemote 

    java:module/CandidatSession!sessions.candidat.CandidatSessionRemote 

    java:jboss/exported/EtestEAProject/EtestMetier/CandidatSession!sessions.candidat.CandidatSessionRemote 

    java:global/EtestEAProject/EtestMetier/CandidatSession!sessions.candidat.CandidatSessionLocal 

    java:app/EtestMetier/CandidatSession!sessions.candidat.CandidatSessionLocal 

    java:module/CandidatSession!sessions.candidat.CandidatSessionLocal 

Answer 1

好的，因为你的软件包如下：

EAR 
|-- WAR 
`-- EJB-JAR 

然后做EJB查找最好的办法是：

ejb:<app-name>/<module-name>/<distinct-name>/<bean-name>!<fully-qualified-classname-of-remote-interface> 

你的情况：

ejb:EtestEAProject/EtestMetier//CandidatSession!sessions.candidat.CandidatSessionRemote 

是的， '//' 是正确的，因为不同的名称为空串。

是得到一个方法执行查询应该是这样的：

public CandidatSessionRemote getEJB() { 
    Hashtable jndiProperties = new Hashtable(); 
    jndiProperties.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming"); 
    Context context = new InitialContext(jndiProperties); 
    return (CandidateSessionRemote) context.lookup("ejb:EtestEAProject/EtestMetier//CandidatSession!sessions.candidat.CandidatSessionRemote"); 
} 

希望这有助于和请让我知道，如果您有任何其他问题。
