无法访问远程EJB

Question

我创建了带有远程和本地接口的 EJB。

@Stateless
public class VendorBean implements VendorBeanLocal, VendorBeanRemote {

    ...

}

@Local
public interface VendorBeanLocal {

    ...

}

@Remote
public interface VendorBeanRemote {

   ...

}

有一些方法可以代替点（在这种情况下并不重要）。

然后将其部署到 glassfish 3.1。它可以从我的客户端 Web 应用程序访问（在同一服务器上作为 war 部署）并且工作正常。但我无法从集成测试中访问它。

我编写了应该由 maven 2 运行的集成测试。我在 glassfish server.log 中查看了该 bean 的 JNDI 名称：

java:global/<my business module name>/VendorBean!<package>.VendorBeanRemote

并编写了测试。但我总是在查找时遇到异常：

测试代码：

Properties p = new Properties();
p.setProperty(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.cosnaming.CNCtxFactory");
p.setProperty("org.omg.CORBA.ORBInitialHost", "localhost");
p.setProperty("org.omg.CORBA.ORBInitialPort", "3700");
Context context = new InitialContext(p);

Object o = context.lookup("java:global/<my business module name>/VendorBean!<package>.VendorBeanRemote");

我很困惑。我读了很多文章，尝试了很多建议，但没有任何效果。

我还尝试在测试中列出一个上下文：

NamingEnumeration<NameClassPair> list = context.list(""); 
while (list.hasMore()) { 
    NameClassPair ncPair = (NameClassPair) list.next(); 
    System.out.print(ncPair.getName() + " (type "); 
    System.out.println(ncPair.getClassName() + ")"); 
}

结果：

<package>.VendorBeanRemote__3_x_Internal_RemoteBusinessHome__ (type com.sun.corba.se.impl.corba.CORBAObjectImpl)
SerialContextProvider (type com.sun.corba.se.impl.corba.CORBAObjectImpl)
java:global (type com.sun.jndi.cosnaming.CNCtx)
INITIAL_GIS (type com.sun.corba.se.impl.corba.CORBAObjectImpl)

所以，看起来像上下文中的 bean。

我做错了什么？请帮忙！

Answer 1

最终我设法解决了这个问题。所以，代码是：

Properties p = new Properties();
p.setProperty(Context.PROVIDER_URL, "corbaname:iiop:localhost:3700");
context = new InitialContext(p);

VendorBeanRemote vendorBean = (VendorBeanRemote) context.lookup("java:global/<my business module name>/VendorBean!<package>.VendorBeanRemote");

重要的是，gf-client.jar 必须位于类路径中。它可以取自
glassfish lib 目录。

Answer 2

如果有人在 glassfish 上的 2 个不同主机之间进行远程 EJB 调用时遇到困难，但上述例外情况除外：
将您的 orb-listener-1 网络地址设置为您的 IP。 （配置中的 ORB / IIOP 侦听器部分）
