Question

当本地java客户端使用此代码从localhost上运行的Glassfish服务器查找JMS ConnectionFactory时，此代码失败。

谁能告诉我为什么？我是如此绝望甚至有用的侮辱是受欢迎的。我把控制台输出放在下面（由我的程序格式化）。

 InitialContext ctx = null;
 ConnectionFactory factory = null;

 // properties - set One
 Hashtable<String,String> env = new Hashtable<String,String> ();
 envTwo.put(Context.INITIAL_CONTEXT_FACTORY,
   "com.sun.enterprise.naming.impl.SerialInitContextFactory");

 env.put(Context.URL_PKG_PREFIXES, 
   "com.sun.enterprise.naming");

 env.put("org.omg.CORBA.ORBInitialPort",
   "3700");

 env.put("org.omg.CORBA.ORBInitialHost",
   "localHost");

 ctx = new InitialContext(env);
 factory = (ConnectionFactory) ctx.lookup("jms/goConnectionFactory");

控制台输出

Properties:
    key: org.omg.CORBA.ORBInitialPort   
    value: 3700
    key: java.naming.factory.initial    
    value: com.sun.enterprise.naming.impl.SerialInitContextFactory
    key: org.omg.CORBA.ORBInitialHost   
    value: localHost
    key: java.naming.factory.url.pkgs   
    value: com.sun.enterprise.naming

InitialContext returned: javax.naming.InitialContext@59494225

 calling ctx.lookup()

The following was written to the .err stream.  All else to .out stream by my program)

我开始知道glassfish 4.1有这个错误，本地客户端无法连接到部署在服务器上的MDB。我尝试了两个ejb项目，它运行得很好。

为什么这些属性无法从glassfish查找ConnectionFactory？
