我必须从我的 Java 应用程序连接到系统的服务器。但是，它失败了，我不明白为什么，因为我已经完成了配置并通过 IP 连接到服务器。错误是：

这是我在 Java 中的配置文件：

org.omg.CORBA.ORBInitRef=NameService=corbaloc:iiop:41.229.0.149:2010/NameService

而系统中的这个文件：

# LISTENER.ORA Network Configuration File: C:\Orant\network\admin\listener.ora
 # Generated by Oracle configuration tools.

LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
  (ADDRESS_LIST =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
       (ADDRESS = (PROTOCOL = TCP)(HOST = 41.229.0.149)(PORT = 1521))
  )
 )
)

SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
  (SID_NAME = demodb)
  (ORACLE_HOME = C:\Orant)
  (GLOBAL_DBNAME = demodb)
)
)
