websphere jndiUnavailCommErr

大家好:
   我近日写一个websphere读取jndi，出现一个很异常，很是头疼。
  
    source code 如下
   
     Properties prop=new Properties();
     prop.put(Context.PROVIDER_URL, "iiop://localhost:2809");
     WsnInitialContextFactory factory=new WsnInitialContextFactory();
      Context context=null;
      try {
     context=factory.getInitialContext(prop);
DataSource datasource=(DataSource)context.lookup("jdbc/SGCRD");
  
    报的异常如下：
       javax.naming.ServiceUnavailableException: A communication failure occurred while attempting to obtain an initial context with the provider URL: "iiop://nwhkg000067:2809".  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.TRANSIENT: initial and forwarded IOR inaccessible  vmcid: IBM  minor code: E07  completed: No]

at com.ubs.starr.test.DataSourceConnectionTest.main(DataSourceConnectionTest.java:23)


    websphere 配置文件：
      <specialEndpoints xmi:id="NamedEndPoint_1295834151497" endPointName="BOOTSTRAP_ADDRESS">
      <endPoint xmi:id="EndPoint_1295834151497" host="NWHKG000" port="2809"/>
    </specialEndpoints>

端口也是2809，而且在websphere的管理界面测试的jdbc/SGCRD也测试成功！

不知群中高手可否帮看看这是什么问题。

原因找到了,主要是因为websphere的hostname和本地的hostname不一致引起的。
