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

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。
