如何从属性文件初始化ORB？

Question

我想从属性文件中的init我的ORB（通常我初始化它像这样，在运行我的例子：./app -ORBInitRef NameService=corbaloc::localhost:2809/NameService）

我写了一个简单的代码：

private static String[] readConfigFile() 
{ 
    Properties prop = new Properties(); 
    String arg[] = new String[1]; 
    try 
    { 
     prop.load(new FileInputStream("config.properties")); 
    } catch (IOException ex) {} 
    arg[0] = prop.getProperty("ORBInitRef"); 
    return arg; 
} 

，然后试图初始化我ORB：

clientsORB = org.omg.CORBA.ORB.init(readConfigFile(), null); 

，但也存在一些误区：

我config.properties文件：

ORBInitRef NameService=corbaloc::localhost:2809/NameService

我做错了什么？ 当我正常启动我的ORB时，一切都很好，所以它不是代码问题，它肯定是从文件初始化的问题。

您必须添加-ORBInitRef到ORB参数也。将它与您正常使用的命令行进行比较。所有的参数都被传递到ORB.init()

config.properties：使用

ORBInitRef NameService=corbaloc::localhost:2809/NameService 

Java代码的它（ReadProps.java）

import java.io.FileInputStream; 
import java.io.IOException; 
import java.util.Properties; 

import org.omg.CORBA.ORB; 

public class ReadProps { 
    public static void main(String[] args) { 
     ORB clientsORB = org.omg.CORBA.ORB.init(readConfigFile(), null); 
    } 

    static String[] readConfigFile() { 
     Properties prop = new Properties(); 
     String[] orbarg = new String[2]; 

     try { 
      // load a properties file 
      prop.load(new FileInputStream("config.properties")); 
      // get the property value and print it out 
      orbarg[0] = "-ORBInitRef"; // <---- NEEDED 
      orbarg[1] = prop.getProperty("ORBInitRef"); 

     } catch (IOException ex) { 
      ex.printStackTrace(); 
     } 
     return orbarg; 
    } 

}
