Server Tomcat v6.0 Server at localhost was unable to start within 45 seconds. If the server requires more time, try increasing the timeout in the server editor.

在eclipse中進行tomcat啟動時報這種異常，有可能是server中的tomcat配置timeout時間有點短。但也有可能是配置檔案出錯了，比如在xml檔案中用尖括號（<>）時沒有進行特殊處理（得用<![CDATA[。。。]]>包起來）等簡單的語法問題。

加長tomcat啟動時timeout的時間：直接修改..\workspace\.metadata\.plugins\org.eclipse.wst.server.core\資料夾下的server.xml檔案中的start-timeout就行，時間長短由你定，單位是秒。
