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 中创建一个新的 Glassfish 服务器实例，编写一个简单的 EJB，部署并成功。

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

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？ “com.sun.enterprise.naming.SerialInitContextFactory”不在类路径中吗？

我很感激你的帮助。

Answer 1

要解决这个问题，只需在客户端的buildpath中添加外部jar“appserv-rt.jar”即可。

您可以在文件夹 ...\glassfishv3\glassfish\lib 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

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，我得到了相同的错误，并且我在控制台中得到“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 包含到类路径中才能正常工作。 (glassfish\lib\gf-client.jar)

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您可能设置的替代端口：

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

Answer 3

在我看来，您试图从未部署在处理连接池的服务器上的应用程序建立连接

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实现 GlassFishORBHelper 接口的 GlassFishORBFactoryImpl.class 的 jar 引起的。
