jacorb中的InvalidName异常

Question

我正在使用Jacorb来实现corba。我已经在端口900上启动了NS。当我尝试启动服务器时，我得到了以下异常

D:\eclipse_workspace\WorkSpace\corba\bin>jaco  hello.MyServer -DORBInitRef.NameService=jacorb::localhost:900
org.jacorb.orb.ORB

    at hello.MyServer.main(MyServer.java:15)

public static void main(String[] args) throws Exception{
    Properties props = new Properties();
    props.setProperty("ORBInitRef","NameService=jacorb::localhost:900");
    System.out.println(System.getProperty("org.omg.CORBA.ORBClass"));
    org.omg.CORBA.ORB orb = org.omg.CORBA.ORB.init(args, props);

    org.omg.CORBA.Object o = orb.resolve_initial_references("NameService");
    NamingContextExt nc = NamingContextExtHelper.narrow( o );

}

Answer 1

NameService引用必须是对包含IOR的文件的引用，例如file://tmp/NS_Ref或URL，例如http://www.testme.not/NS_Ref，或者仅仅是corbaloc/corbaname URL，例如corbaloc:iiop:1.2@host1:3075/NameService

最后一个是最常见的。您可以将其缩短，例如，缩短为corbaloc::localhost:900/NameService
