【问题描述】：
    最近觉得有必要亲自实践下ejb的最简单的例子，果然问题嗷嗷多，如下:
javax.naming.NamingException: Lookup failed for 'TestServiceBean' in SerialContext[myEnv={java.naming.provider.url=http://localhost:3700, java.naming.factory.initial=com.sun.enterprise.naming.SerialInitContextFactory, java.naming.factory.url.pkgs=com.sun.enterprise.naming, java.naming.factory.state=com.sun.corba.ee.impl.presentation.rmi.JNDIStateFactoryImpl} [Root exception is javax.naming.NamingException: Unable to acquire SerialContextProvider for SerialContext[myEnv={java.naming.provider.url=http://localhost:3700, java.naming.factory.initial=com.sun.enterprise.naming.SerialInitContextFactory, java.naming.factory.url.pkgs=com.sun.enterprise.naming, java.naming.factory.state=com.sun.corba.ee.impl.presentation.rmi.JNDIStateFactoryImpl} [Root exception is java.lang.RuntimeException: Orb initialization erorr]]

【解决方案】：   
    引用gf-client.jar，并且是指向glassfish中的..\glassfish3\glassfish\lib下的

【问题分析】：
    很容易看出来是Context初始化有问题，以至于后边的lookup都没法掉。
    你得保证你的classpath中有引用gf-client.jar，
    特别注意这里的引用jar一定是指向glassfish中的..\glassfish3\glassfish\lib下的，
    这样他会在添加classpath顺便填加相关的jar包。
    如果你打开gf-client.jar下META-INF/MANIFEST.MF文件时就会发现如下信息(想必你已经知道我要说些什么了，
    当然你也是可以手动添加这些jar到你的classpath来代替gf-client.jar，反正随便你的):

【问题扩展】：
   对于glassfish中对无状态会话的ejb3的bean的jndi查找，特贴两个成功的方法：
Test.java:
    ...
    @Test
    public void TestSayHello() throws NamingException {
        Properties p = new Properties();
        // method 1
//        p.put("java.naming.factory.initial", "com.sun.enterprise.naming.SerialInitContextFactory");
//        p.put("java.naming.factory.url.pkgs", "com.sun.enterprise.naming");
//        p.put("java.naming.factory.state", "com.sun.corba.ee.impl.presentation.rmi.JNDIStateFactoryImpl");
//        p.put("org.omg.CORBA.ORBInitialHost", "127.0.0.1");
//        p.put("org.omg.CORBA.ORBInitialPort", "3700");
       
        // method 2
        p.setProperty(Context.INITIAL_CONTEXT_FACTORY, "com.sun.enterprise.naming.SerialInitContextFactory");
        p.setProperty(Context.PROVIDER_URL, "http://localhost:3700");
       
        // if orb init error occurs please see "/libs/readme.txt"
        Context context = new InitialContext(p);
        // method 1: 对应@Stateless(mappedName="TestServiceBean")
//        TestService ts = (TestService)context.lookup("TestServiceBean");
        // method 2: 对应@Stateless
        TestService ts = (TestService)context.lookup("org.cy.services.TestService");
        System.out.println(ts.sayHello()); //Hello EJB!
    }
