我不能創建一個SipProvider- MjSip庫

我是MjSip的新手，我想創建一個SipProvider類的實例。所以我又寫道這個小代碼，但得到一些錯誤：我不能創建一個SipProvider- MjSip庫

sip_provider = new SipProvider("192.168.0.254",5060);

這裏是錯誤堆棧：

java.io.FileNotFoundException: log\192.168.0.254.5060_events.log (The system cannot find the path specified)

我使用LAN網絡和IP地址是有效的。爲什麼會發生這種情況？請幫助我！

對不起。我的錯。我沒有在應用程序根目錄中創建日誌文件夾。:) –

您可以在此處添加答案並進行驗證。 – Nizam

是的，你能添加一個答案嗎？ –

沒有日誌文件夾。您需要創建一個文件夾。或者你應該給一個特定的目錄。

 String home = System.getProperty("user.home");    
     File f = new File(home +"//"+SipStack.log_path);   
     try { 
      if (!f.exists() || !f.isDirectory()) 
      {              
       JOptionPane.showMessageDialog(null,home +"//"+SipStack.log_path + " dosyası oluşturulacak"); 
       File dir = new File(home +"//"+SipStack.log_path); 
       dir.mkdir(); 
      } 
     } catch (Exception e) { 
      JOptionPane.showMessageDialog(null,"Log klasörü oluşturulamadı"); 
     } 
    } catch (Exception ex) { 
    } 

    if (SipStack.debug_level>0) 
    { 
    String home = System.getProperty("user.home");   
    String filename=home+"//"+SipStack.log_path+"//"+via_addr+"."+host_port; 
    log=new RotatingLog(filename+"_events.log",SipStack.debug_level,SipStack.max_logsize*1024,SipStack.log_rotations,SipStack.rotation_scale,SipStack.rotation_time); 
    message_log=new RotatingLog(filename+"_messages.log",SipStack.debug_level,SipStack.max_logsize*1024,SipStack.log_rotations,SipStack.rotation_scale,SipStack.rotation_time); 
    }
