獲取的錯誤，同時將字符串轉換回CORBA對象引用

這是我的服務器類：獲取的錯誤，同時將字符串轉換回CORBA對象引用

import java.io.FileNotFoundException; 
import java.io.PrintWriter; 

import org.omg.CORBA.ORB; 
import org.omg.CORBA.ORBPackage.InvalidName; 
import org.omg.PortableServer.POA; 
import org.omg.PortableServer.POAHelper; 
import org.omg.PortableServer.POAManagerPackage.AdapterInactive; 
import org.omg.PortableServer.POAPackage.ObjectNotActive; 
import org.omg.PortableServer.POAPackage.ServantAlreadyActive; 
import org.omg.PortableServer.POAPackage.WrongPolicy; 

public class BehaviorServer { 

    /** 
    * @param args 
    * @throws InvalidName 
    * @throws WrongPolicy 
    * @throws ServantAlreadyActive 
    * @throws ObjectNotActive 
    * @throws FileNotFoundException 
    * @throws AdapterInactive 
    */ 
    public static void main(String[] args) throws InvalidName, ServantAlreadyActive, WrongPolicy, ObjectNotActive, FileNotFoundException, AdapterInactive { 
     ORB orb=ORB.init(args,null); 
     POA rootPOA=POAHelper.narrow(orb.resolve_initial_references("RootPOA")); 

     BehaviorImpl aBehavior=new BehaviorImpl(); 
     byte[] id=rootPOA.activate_object(aBehavior); 
     org.omg.CORBA.Object ref=rootPOA.id_to_reference(id); 

     String ior=orb.object_to_string(ref); 
     System.out.println(ior); 
     PrintWriter file=new PrintWriter("ior.txt"); 
     file.println(ior); 

     rootPOA.the_POAManager().activate(); 
     orb.run(); 
    } 

}

我的客戶：

public class BehaviorClient { 

    /** 
    * @param args 
    * @throws IOException 
    */ 
    public static void main(String[] args) throws IOException { 
     // TODO Auto-generated method stub 
     ORB orb=ORB.init(args,null); 
     BufferedReader br=new BufferedReader(new FileReader("ior.txt")); 
     String ior=br.readLine(); 
     br.close(); 

     org.omg.CORBA.Object o=orb.string_to_object(ior); 
     Behavior aBehavior=BehaviorHelper.narrow(o); 
     aBehavior.eat(); 

    } 

}

我得到的錯誤：

Nov 02, 2014 11:58:00 PM com.sun.corba.se.impl.orb.ORBImpl string_to_object 
WARNING: "IOP00110201: (BAD_PARAM) Null parameter"

我已經看過發佈在這個問題上的其他問題，但它並沒有幫助我。擡頭一看這些： Bad_Param in java CORBA 試圖初始化我的ORB

ior爲空，這意味着oir.txt是空的，這是無法關閉文件時，你寫它引起的。在println()之後添加close()。
