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;
}
}
