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 ？是不是在类路径中的"com.sun.enterprise.naming.SerialInitContextFactory"？

我感谢您的帮助.

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".
