Java Wurfl实现异常

我有以下错误，请帮助我哪里做错了

ERROR n.s.wurfl.core.GeneralWURFLEngine - cannot initialize: java.lang.NullPointerException: in is null
java.lang.NullPointerException: in is null
    at java.util.zip.ZipInputStream.<init>(ZipInputStream.java:100) ~[na:1.7.0_72]
    at java.util.zip.ZipInputStream.<init>(ZipInputStream.java:79) ~[na:1.7.0_72]

    at net.sourceforge.wurfl.core.resource.FileLoader.openInputStream(FileLoader.java:230) ~[wurfl-1.5.jar:na]

显示的输出：

debugging request: org.apache.catalina.core.ApplicationHttpRequest@133b7e9
==wurflholder: net.sourceforge.wurfl.core.GeneralWURFLEngine@6f28c4 
==Holder: String net.sourceforge.wurfl.core.GeneralWURFLEngine@6f28c4

但它在下面的代码中给出了错误

try{
    device = holder.getDeviceForRequest(request); //This is giving exception 

    }
    catch(Exception e ){e.printStackTrace();}

---

请告知

类路径中没有

/web inf/

目录，这导致引发异常

---

尝试将您的

wurfl.zip

放入

/web inf/classes

中，以便正确加载。

是的，我这样做了，砰的一声！它跑了。我访问了帖子回答自己，但你已经做到了！干杯
