the client code is this
客户端代码是这样的
Properties props = new Properties();
props.setProperty("java.naming.factory.initial", "com.sun.enterprise.naming.SerialInitContextFactory");
props.setProperty("java.naming.factory.url.pkgs", "com.sun.enterprise.naming");
props.setProperty("java.naming.factory.state", "com.sun.corba.ee.impl.presentation.rmi.JNDIStateFactoryImpl");
InitialContext ic = new InitialContext(props);
HelloRemote remote = (HelloRemote) ic.lookup("helloRemote");
System.out.println(remote.echo("john"));
Do you know why ? is it "com.sun.enterprise.naming.SerialInitContextFactory" not in the classpath ?
你知道为什么吗 ？是不是“com.sun.enterprise.naming.SerialInitContextFactory”不在类路径中？

I appreciate your help.
我感谢您的帮助。

To solve this issue, you just need to add external jar "appserv-rt.jar" in the buildpath of the client.
要解决这个问题，您只需要在客户端的构建路径中添加外部jar“appserv-rt.jar”。
You can find it in the folder ...\glassfishv3\glassfish\lib
您可以在文件夹 ...\glassfishv3\glassfish\lib 中找到它
Or create a package with this jar and all its dependencies to add it in the BP
或者用这个jar包和它的所有依赖创建一个包，把它添加到BP中
This is my code
这是我的代码
InitialContext ctx = new InitialContext();
HelloWorld helloWorldRemote = (HelloWorld) ctx.lookup("ejb/helloWorldBeanJndiName");
System.out.println(helloWorldRemote.sayHello());
Without the jar file, i got the same error and with I get "Hello" in the console.
没有 jar 文件，我遇到了同样的错误，并且在控制台中出现了“Hello”。

Judging from the properties you set this must be a standalone client.
从您设置的属性来看，这必须是一个独立的客户端。
Make sure you include the gf-client.jar to your classpath for this to work. (glassfish\lib\gf-client.jar)
确保将 gf-client.jar 包含到类路径中以使其正常工作。(glassfish\lib\gf-client.jar)
You also don't need to set the properties you set. To specify a non-localhost location of your server or alternative port however you might set:
您也不需要设置您设置的属性。要指定服务器的非本地主机位置或替代端口，您可以设置：
prop.setProperty("org.omg.CORBA.ORBInitialHost", "localhost");
prop.setProperty("org.omg.CORBA.ORBInitialPort", "3700");
You also might want to go over "How do I access a Remote EJB component from a stand-alone java client?" at: http://glassfish.java.net/javaee5/ejb/EJB_FAQ.html#StandaloneRemoteEJB
您可能还想了解“如何从独立的 Java 客户端访问远程 EJB 组件？” 在：http: //glassfish.java.net/javaee5/ejb/EJB_FAQ.html#StandaloneRemoteEJB

Seems to me like your trying to establish a connection from an application that is not deployed on your server which handles the connnectionpool
在我看来，您尝试从未部署在处理连接池的服务器上的应用程序建立连接

I had similar error:
我有类似的错误：
java.lang.RuntimeException: Orb initialization erorr at org.glassfish.enterprise.iiop.api.GlassFishORBHelper.getORB(GlassFishORBHelper.java:180)
which was caused by
这是由
java.lang.NullPointerException at org.glassfish.enterprise.iiop.api.GlassFishORBHelper.getORB(GlassFishORBHelper.java:152)
My solution was to add jar that contains GlassFishORBFactoryImpl.class that implements the GlassFishORBHelper interface.
我的解决方案是添加包含实现 GlassFishORBHelper 接口的 GlassFishORBFactoryImpl.class 的 jar。
