如何在Windows中爲Apache Tomcat配置xuggle

我一直在開發Windows平臺上使用Netbeans和Tomcat的視頻共享Web應用程序（如youtube）。我想在視頻上傳後立即生成視頻文件的縮略圖。所以在網上搜索我找到了一個叫做Xuggle的東西。我在我的Tomcat的lib文件夾中安裝了Xuggler。我已經設置了必要的環境變量。當我運行一個Java應用程序，我得到的結果，但是當我做同樣的Java Web應用程序，我得到了以下錯誤：如何在Windows中爲Apache Tomcat配置xuggle

@ pd40 >>>我重新安裝了Xuggler（這次在C：\ Program Files，I 。重新啓動我的電腦安裝後，我設置我的環境變量如下：

XUGGLE_HOME = C：\ Program Files文件（x86）的\ Xuggle

CLASSPATH =。; C：\ Apache Tomcat 6.0.26 \ Apache Tomcat 6.0.26 \ lib \ commons-cli.jar; C：\ Apache Tomcat 6.0.26 \ Apache Tomcat 6.0.26 \ lib \ logback -classic.jar; C：\ Apache Tomcat 6.0.26 \ Apache Tomcat 6.0.26 \ lib \ logback-core.jar; C：\ Apache Tomcat 6.0.26 \ Apache Tomcat 6.0.26 \ lib \ slf4j-api.jar ; C：\ Apache Tomcat 6.0.26 \ Apache Tomcat 6.0.26 \ lib \ xuggle-xuggler.jar; C：\ Apache Tomcat 6.0.26 \ Apache Tomcat 6.0.26 \ lib \ xuggle-xuggler-test.jar;

PATH = C：\ Program Files（x86）\ Xuggle \ bin; C：\ Apache Tomcat 6.0.26 \ Apache Tomcat 6.0.26 \ bin; C：\ Apache Tomcat 6.0.26 \ Apache Tomcat 6.0 .26 \ lib; C：\ Program Files（x86）\ Xuggle \ lib

我在Tomcat的\ lib文件夾中複製了Xuggle/java/jars（6個jar文件）的jar文件並設置了它們的CLASSPATH。

現在我仍然遇到問題，當我在Web應用程序中這樣做時，但獨立的Java應用程序很好地生成了圖像。發生了什麼事？當我把它上傳被上傳的視頻，但不生成縮略圖，我得到以下錯誤...
