did u compile ur .idl file?

[jinket]

已经编译了.idl文件了，生产了6个.java的文件，而且我已经把它编译为.class文件了。服务端执行正常，执行客户端时就报错～

[redex]

执行客户端时，某些重要参数没有加上？ 我用的是ejb，客户端调用
服务器端时， 写的参数很多啊。做个参考吧。

我用delhpi的服务 java的客户 visibroker 4.5.1 jdk1.3.01

// Client.java
import org.omg.CosNaming.*;
import org.omg.CORBA.ORBPackage.*;
import InhopeCAServer.*;
public class Client {

public static void main(String[] args) {
// Initialize the ORB.
org.omg.CORBA.ORB orb = org.omg.CORBA.ORB.init(args,null);

// Locate an account manager.
IInhopeCA manager = IInhopeCAHelper.bind(orb, "Co_InhopeCA");
// use args[0] as the account name, or a default.
String carid = args.length > 0 ? args[0] : "0587CA";
// Request the account manager to open a named account.
String returnInfo =manager.GetCertInfo(carid);

System.out.print(returnInfo);
}

}



问题是
Exception in thread "main" org.omg.CORBA.OBJECT_NOT_EXIST:
