Question

我用远程和本地接口创建了EJB。

@Stateless
public class VendorBean implements VendorBeanLocal, VendorBeanRemote {

    ...

}

@Local
public interface VendorBeanLocal {

    ...

}

@Remote
public interface VendorBeanRemote {

   ...

}

有一些方法而不是点（在这种情况下无关紧要）。

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（在同一台服务器上部署为war）并且工作正常。但我无法通过集成测试访问它。

我编写了集成测试，它应该由maven 2运行。我在glassfish server.log中查看了这个bean的JNDI名称：

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

并写了测试。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，但没有任何作用。

我还尝试在测试中列出上下文：

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，在上下文中看起来像bean。

我做错了什么？请帮忙！

Answer 1

最终我成功解决了这个问题。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。它可以从中获取 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，则上述情况除外：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）

无法访问远程EJB
