websphere remote ejb调用corba.object_not_exist locatereply.unknown_object次要代码：C01

Question

我在同一台机器上有两个本地WebSphere7应用程序服务器（两个配置文件）。只是默认安装，没有自定义配置。其中之一公开了一个部署为EJB3会话bean的服务，该会话bean具有ejb/edu/test/ejbfacade JNDI名称。

我编写了一个简单的JUnit集成测试，它远程调用一个方法：

@Test
public void testCall() throws Exception {
    Hashtable props = new Hashtable();
    props.put(Context.PROVIDER_URL, "corbaloc:iiop:localhost:2811");
    props.put(Context.INITIAL_CONTEXT_FACTORY, "com.ibm.websphere.naming.WsnInitialContextFactory");
    props.put("org.omg.CORBA.ORBClass", "com.ibm.CORBA.iiop.ORB");
    InitialContext initialContext = new InitialContext(props);

    Object obj = initialContext.lookup("cell/nodes/myNode03/servers/server1/ejb/edu/test/EjbFacade");
    EjbFacade facade = (EjbFacade) PortableRemoteObject.narrow(obj, EjbFacade.class);
    facade.doSomething();
}

ibm-web-bnd.xmi

  <ejbRefBindings xmi:id="EjbRefBinding_1386431681401" jndiName="ejb/edu/test/EjbFacade">
      <bindingEjbRef href="WEB-INF/web.xml#EjbRefBinding_EjbFacade"/>
  </ejbRefBindings>

web.xml

  <ejb-ref id="EjbRefBinding_EjbFacade">
      <ejb-ref-name>ejb/edu/test/EjbFacade</ejb-ref-name>
      <ejb-ref-type>Session</ejb-ref-type>
      <home/>
      <remote>edu.test.EjbFacade</remote>
  </ejb-ref>

我正在使用本地JNDI名称：java：comp/env/EJB/edu/test/ejbfacade在websphere管理控制台中映射到corbaloc:iiop:localhost:2811/cell/nodes/mynode03/servers/server1/EJB/edu/test/ejbfacade的servlet中进行相同的EJB调用。

Caused by: javax.naming.ServiceUnavailableException: A communication failure
occurred while attempting to obtain an initial context with the provider URL: 
"corbaloc:iiop:localhost:2811/cell/nodes/myNode03/servers/server1/ejb/edu/test/EjbFacade". 
Make sure that any bootstrap address information in the URL is correct and that the target 
name server is running.  A bootstrap address with no port specification defaults to port 2809.
Possible causes other than an incorrect bootstrap address or unavailable name server 
include the network environment and workstation network configuration. 
[Root exception is org.omg.CORBA.OBJECT_NOT_EXIST: LocateRequest 6 received    
LocateReply.UNKNOWN_OBJECT  vmcid: IBM  minor code: C01  completed: No]

我应该在WAS控制台中配置什么JNDI名称？为什么相同的代码在JUnit下工作，但在Servlet中失败了？

您需要uniqueServerName选项。请参阅InfoCenter中应用程序访问问题主题的“在同一主机上运行的两台同名服务器正在被用于互操作”部分。
