eclipse glassfish 3，客户端错误

Question

我正在使用最新的Eclipse在Glassfish 3下开发EJB 3.我在Eclipse中创建了一个新的Glassfish服务器实例，编写了一个简单的EJB，已经部署并成功完成。

现在我写了一个客户端，但它总是给我这样的错误

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"));

你知道为什么吗 ？ 是不是在类路径中“com.sun.enterprise.naming.SerialInitContextFactory”？

我感谢您的帮助。

Answer 1

要解决此问题，您只需在客户端的构建路径中添加外部jar“appserv-rt.jar”。

你可以在... \\ glassfishv3 \\ glassfish \\ lib文件夹中找到它

或者使用此jar及其所有依赖项创建一个包，以将其添加到BP中

这是我的代码

InitialContext ctx = new InitialContext();
HelloWorld helloWorldRemote = (HelloWorld) ctx.lookup("ejb/helloWorldBeanJndiName");
System.out.println(helloWorldRemote.sayHello());

没有jar文件，我得到了同样的错误，我在控制台中得到“Hello”。

Answer 2

从您设置的属性来看，这必须是一个独立的客户端。

确保将gf-client.jar包含在类路径中以使其正常工作。 （的glassfish \\ lib中\\ GF-client.jar中）

您也不需要设置您设置的属性。 要指定服务器或备用端口的非本地主机位置，您可以设置：

prop.setProperty("org.omg.CORBA.ORBInitialHost", "localhost");
prop.setProperty("org.omg.CORBA.ORBInitialPort", "3700");

Answer 3

在我看来，就像你试图从未在服务器上部署的应用程序建立连接来处理连接池一样

Answer 4

我有类似的错误：

java.lang.RuntimeException: Orb initialization erorr at org.glassfish.enterprise.iiop.api.GlassFishORBHelper.getORB(GlassFishORBHelper.java:180)

这是由

java.lang.NullPointerException at org.glassfish.enterprise.iiop.api.GlassFishORBHelper.getORB(GlassFishORBHelper.java:152)

我的解决方案是添加包含GlassFishORBFactoryImpl.class的jar，它实现了GlassFishORBHelper接口。
