我有一個相當艱難的時間,試圖利用interprolog的Java/Prolog的幫助 - 故障排除

我有一些代碼,試圖調用一個序言命令,問題是我的序言數據庫的實際負荷。下面是代碼:

myEngine = new NativeEngine(); 
    myEngine.consultFromPackage("userlist.p", LoginHandler.class); 
    boolean x = myEngine.deterministicGoal("has_access(user,pass)"); 

當我運行程序序言初始化精細,它會嘗試尋找userlist.p這是在同一個包(的代碼第二行),然後它將引發此錯誤:

Exception in thread "AWT-EventQueue-0" com.declarativa.interprolog.util.IPException: Problem consulting from package archive:C:\Users\Keval\AppData\Local\Temp\IP_6971701367857416872\userlist.p

我看着爲consultFromPackage代碼:

public void consultFromPackage(String filename,Object requester){ 
     String path = cleanPath(copyToTemp(filename,requester).getPath()); 
     path = unescapedFilePath(path); 
     progressMessage("consultFromPackage:"+path); 
     if (!command("consult('"+path+"')")) 
     throw new IPException("Problem consulting from package archive:"+path); 
    } 

,但我似乎無法得到的problem..i根知道這是所有有點遠,但任何幫助讚賞在這一點上。

感謝

我的猜測是,有一些與路徑腳麻是沒有找到它預計的位置user.p。嘗試從最小的命令行測試程序開始,以瞭解這些庫如何在簡單的原型中工作。
