Tomcat無法在eclipse上啓動

Question

在Eclipse中的Java EE項目中啓動tomcat 7.0時遇到了一些問題。啓動服務器時出現超時錯誤。 我還沒有弄清楚什麼是錯的。 我嘗試將超時限制增加到1800s，但不會改變任何內容。

這裏是日誌當Tomcat嘗試啓動：

感謝您迴應

Answer 1

INFO: Server startup in 1846 ms

具體來說，Tomcat作爲成功啓動（在你的堆棧跟蹤的最後一行所示）的應用程序服務器這是名爲test的Web應用程序無法部署爲丟失的依賴（Apache的庫）作爲的結果你可以從

Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext[/test]] Caused by: java.lang.NoClassDefFoundError: Lorg/apache/commons/logging/Log;

看到here

下載缺少的依賴性，以免後患，複製你從上面的鏈接下載的公共圖書館罐子並將其放置在日e WEB-INF\lib部署包（文件夾或.war文件）的test文件夾。

另外，

下載並安裝Apache下議院從共享網站here和日誌庫的最新副本複製到TOMCAT_HOME\common\lib文件夾（如果它不存在，創建路徑）。 TOMCAT_HOME是指你的tomcat安裝文件夾。不要將罐子複製到多個地點，這會在以後造成問題

Answer 2

Tomcat是無法啓動由於安裝的web應用的丟失的依賴。 從您的堆棧跟蹤（去除的嗡嗡聲：P）

...[blah blah]... 
Caused by: java.lang.ClassNotFoundException: org.apache.commons.logging.Log 
at org.apache.catalina.loader.WebappClassLoader.loadClass [...] 
...[blah blah]... 
GRAVE: A child container failed during start 
...[blah blah]... 

嘗試刪除所有已部署的Web應用程序，並重新開始。如果Tomcat會啓動，那麼你可以試着弄清楚你的web應用程序導致了哪些混亂。
