將Tomcat文件從一台服務器傳輸到另一台服務器

[英]Transferring Tomcat files from one server to another

問題描述

我是新手，因此有人要求我將內部Tomcat服務器和Web應用程序移至另一個（長話說，我為什么要執行此任務）。 我不是100％知道這里涉及什么。 該網站主要是用JSP編寫的，對此我知之甚少。 到目前為止，我所做的是安裝Tomcat 6.0（這是原始服務器上的版本），復制了包含站點的webapps文件夾，並將其放置在新的webapps文件夾中。 並不奇怪，它不起作用，但是需要診斷或重新配置方面的幫助才能使它再次起作用。 有什么幫助嗎？

好像您有問題 

 pst = con.prepareStatement("select m.parent_menu as mainMenu,m.menu_title as subMenu,a.menu_title as articleTitle,a.article_id as articleId from articles a left join menu m on m.menu_id = a.menu_id where a.menu_title is not null order by parent_menu desc,menu_order");

您是否已在新服務器中建立數據庫連接？

而且您可能應該閱讀服務器的日志（如最后一行所示）

希望這個對你有幫助。

問候，帕特里克

謝謝-問題是我從庫中丟失了jtds-1.3.1.jar文件。 下載文件，將其放置並得到一個新的錯誤，該錯誤很容易解決。 我必須用新的SQL主機名更新HTML / JSP文件，這很好。

謝謝你的幫助
