java-如何从属性文件初始化ORB?

我想从属性文件中初始化我的ORB(通常在运行示例时,我是这样初始化它的:./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;
}

然后尝试初始化我的球体:

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

但是有一些错误:

我的config.properties文件:

ORBInitRef NameService = corbaloc :: localhost:2809 / NameService

我做错了什么?通常,当我初始化我的ORB时,一切都很好,所以它不是代码问题,而是文件初始化的问题.

解决方法:

您还必须将-ORBInitRef添加到ORB参数.将其与您通常使用的命令行进行比较.所有参数都必须传递给ORB.init()

config.properties:

ORBInitRef NameService=corbaloc::localhost:2809/NameService 

使用它的Java代码(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;
    }

}
