ECLIPSE：java.lang.NoClassDefFoundError：無法初始化類****

Question

首先，對於所有麻煩我深表歉意。

情況就是這樣：上周，我在Java Web應用程序上做得很好（沒有問題，也沒有問題，都完美無缺）。 然后停電關閉計算機，該項目無法正常工作（我運行了它，這是我在帖子末尾獲得的stacktrace）

我已經找到了很多關於java.lang.NoClassDefFoundError的文檔以及很多解決方案：

• 像：將所有依賴項放在項目的類路徑中。
• 像：它的運行時問題，無法正確加載該類。
• 還有更多。

我嘗試了所有解決方案，其中大多數已經在項目中。

該項目的結構為：

• xxxxxAdmin-> xhtml所在的位置。
• xxxxxJar->主類和休眠conf所在的位置。
• xxxxxWar-> servlet所在的位置。 （我知道這是徒勞的：S）

“ xxxxx”不是項目的名稱，但我不能在這里輸入。 名稱是這樣的：'company.projectname'。

我沒有主意，所以請...如果這能引起別人的注意，我將不勝感激。

如果我想念什么，請告訴我。 謝謝大家
