How to init ORB from property file?

问题:

I would like to init my ORB from property file (normally I init it like this, while running my examples: ./app -ORBInitRef NameService=corbaloc::localhost:2809/NameService)

I wrote a simple code:

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; } 

and then tried to init my orb:

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

but there are some errors:

My config.properties file:

ORBInitRef NameService=corbaloc::localhost:2809/NameService

What I did wrong? When I init my ORB normally, everything is great, so its not the code issue, its definitely problem with initialization from file.

回答1:

You have to add -ORBInitRef to the ORB arguments also. Compare it to the commandline you normaly use. ALL the arguments have to be passed to the ORB.init()

config.properties:

ORBInitRef NameService=corbaloc::localhost:2809/NameService  

Java Code using it (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;     }  }
