加载页面时未加载的值

标签： java eclipse jsp tomcat

我正在编写一个Web应用程序，当index.jsp打开时，必须从数据库中提取值并显示为标题。在我目前的场景中，当我从我的eclipse运行项目时，它显示了值，当我尝试通过将项目导出到war并从tomcat单独部署它来执行相同操作时，它无法正常工作。以下是文件。

请告诉我哪里出错了。我该如何解决这个问题。这在Eclipse浏览器中工作正常，但在外部浏览器中没有。

以下是我的输出

在Eclipse中部署

enter image description here

在Tomcat Web GUI中外部部署为WAR

enter image description here

这里针对Eclipse我使用了Tomcat 8.0，外部使用了7.0，在导出到WAR时，我取消选中了Server Compatibility复选框。

在Eclipse中，端口是8080，对于外部Tomcat，我使用了9090（只是为了确保没有混淆）。
