原因：java.lang.NoClassDefFoundError：當tomcat / lib下存在類時？

Question

我有兩次戰爭都使用一個特定的jar（ ehcache-core.jar ）。 我確實將jar放在<Tomcat_Home>\\lib 。 但是，當我啟動服務器時，我的應用程序拋出以下錯誤，其中ehcache-core.jar下存在類

Answer 1

錯誤消息說：

無法初始化類net.sf.ehcache.CacheManager

在日志文件中進一步檢查，對於在CacheManager或其依賴類之一初始化期間引發的某些異常，應該有一個堆棧跟蹤。 解決該異常的原因，此問題也將得到解決。
