@齐国隆冬强 你好，想跟你请教个问题：

问题 : 当我黄色部分为5个参数的时候 

       path[0] = new NameComponent("TMF_MTNM","Class");
        path[1] = new NameComponent("HUAWEI","Vendor");
        path[2] = new NameComponent("Huawei/U2000","EmsInstance");
        path[3] = new NameComponent("2.0","Version");
        path[4] = new NameComponent("Huawei/U2000","EmsSessionFactory_I");

运行到这里      obj= ncRef.resolve(path); 会给我报如下错误

CosNaming.NamingContextPackage.NotFound: IDL:omg.org/CosNaming/NamingContext/NotFound:1.0
    at CosNaming.NamingContextPackage.NotFoundHelper.read(NotFoundHelper.java:72)
    at CosNaming._NamingContextStub.resolve(_NamingContextStub.java:151)
    at clinet.CorbaClientPtnHw.main(CorbaClientPtnHw.java:93)

也就是 CosNaming.NamingContextPackage.NotFound的错误,试过很多方法都么有办法解决.

当参数为2个的时候  obj= ncRef.resolve(path); 这个可以运行可以得到obj的值

但是这个值放到后面做参数的时候    emsSessionFactory_I = EmsSessionFactory_IHelper.narrow(obj);提示参数不全
  所以我想在问一下

       path[0] = new NameComponent("TMF_MTNM","Class");
        path[1] = new NameComponent("HUAWEI","Vendor");
        path[2] = new NameComponent("Huawei/U2000","EmsInstance");
        path[3] = new NameComponent("2.0","Version");
        path[4] = new NameComponent("Huawei/U2000","EmsSessionFactory_I");

这里面中的TMF_MTNM 这些值是固定的吗 >??
