Tomcat 7啓動問題：無法初始化類org.apache.tomcat.util.descriptor.DigesterFactory

好的。有一次，我有Tomcat（7）正常工作。現在不是。我不知道我可能會搞砸了。（但我認爲這發生在我在NetBeans中設置一個與Tomcat一起使用的web項目。）Tomcat 7啓動問題：無法初始化類org.apache.tomcat.util.descriptor.DigesterFactory

我在OS X 1.8.5上，使用Java 1.7.0_51。

我catalina.out的是這樣的：

我曾嘗試重新安裝Tomcat的，但問題仍然存在。我會非常感謝我能得到的任何指示。

這是SO的話題。請閱讀[FAQ]和[Ask]。也許適用於[webmasters.se]或[sf]。 –

聽起來像您可能已經編輯了Tomcat的xml配置文件之一，並可能出現錯誤。 'digester'是一個讀取xml文件並創建相關對象配置的組件，但是如果在xml文件中出現某些問題，它可能會導致您看到的內容。 – mikemil

感謝您的提示，但我不明白這是怎麼一個問題，當它給我一個新的安裝tomcat完全相同的錯誤？ – edvarda

同樣確切的問題發生在我身上。你可能已經下載了你自己的servlet.jar文件，而不是使用tomcat的。看看你的/ Library/Java/Extensions /文件夾（或者你放入jar文件的文件夾），然後刪除servlet.jar文件。卡塔利娜跑，它現在應該工作
