不要初始化GeneralWURFLEngine

Question

我用wurfl檢測手機上的設備。 我初始化GeneralWURFLEngine但它不能初始化

我的代碼：

public static final String path = "wurfl.zip"; 
private static ThreadLocal<WURFLEngine> wulEngine = new ThreadLocal<WURFLEngine>() { 
     protected WURFLEngine initialValue() { 
      return new GeneralWURFLEngine(path); 
     }; 
    }; 
Device device = wulEngine.get() 
        .getDeviceForRequest(userAgentString); 

錯誤：

ERROR core.GeneralWURFLEngine (GeneralWURFLEngine.java:274) - cannot initialize: net.sourceforge.wurfl.core.resource.exc.WURFLResourceException: WURFL unexpected exception 
net.sourceforge.wurfl.core.resource.exc.WURFLResourceException: WURFL unexpected exception

     at net.sourceforge.wurfl.core.GeneralWURFLEngine.getDeviceForRequest(GeneralWURFLEngine.java:41 

如何我可以修復的bug？感謝您的幫助

這裏是一個工作示例來初始化GeneralWURFLEngine

import net.sourceforge.wurfl.core.Device; 
import net.sourceforge.wurfl.core.EngineTarget; 
import net.sourceforge.wurfl.core.GeneralWURFLEngine; 

public static void main(String[] args) { 
    GeneralWURFLEngine wurfl = new GeneralWURFLEngine("wurfl.zip"); 
    wurfl.setEngineTarget(EngineTarget.performance); 
    Device device = wurfl.getDeviceForRequest("User-Agent/5 FooBar"); 
    System.out.println(device.getCapability('model_name')); 
}
