将Tomcat文件从一台服务器传输到另一台服务器

时间：2016-03-18 10:18:32

标签： java jsp tomcat

我是新手，我已经被工作要求将内部Tomcat服务器和webapps移动到另一个（长篇故事为什么我完成了这个任务）。我不是100％确定这里涉及到什么。该网站主要使用JSP编写，我对此知之甚少。 到目前为止我所做的是安装Tomcat 6.0（这是原始服务器上的版本），复制包含该站点的webapps文件夹并将其放在新的webapps文件夹中。并不感到意外，它没有工作，但需要帮助诊断或重新配置，以使其再次工作。有什么帮助吗？

好像你有问题

 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");

您是否在新服务器中设置了数据库连接？

可能你应该阅读服务器的日志（如最后一行所示）

希望这会有所帮助。

答案 1 :(得分：1)

谢谢 - 问题是我错过了库中的jtds-1.3.1.jar文件。 下载文件，放置它并得到一个新错误，一个很容易解决的错误。我不得不用新的SQL主机名更新HTML / JSP文件，这很好。

感谢您的帮助
