corba接口连接服务端

[qq_17839585]

Java程序：
EmsSessionFactory_I EmsSessionFactory = EmsSessionFactory_IHelper.narrow(obj);
NmsSession_IImpl pNmsSessionServant = new NmsSession_IImpl();
NmsSession_I NmsSession = pNmsSessionServant._this(m_orb);
EmsSession_IHolder emsSessionInterfaceHolder = new EmsSession_IHolder();

EmsSessionFactory.getEmsSession(Constants.ServerUser, Constants.ServerPassword, NmsSession, emsSessionInterfaceHolder);

m_emsSessionI = emsSessionInterfaceHolder.value;
m_emsSessionI.ping();
