Java HTML 5视频标记无法从Tomcat工作（已编辑）,java,html,jakarta-ee,tomcat,tomcat7,Java,Html,Jakarta Ee,Tomcat,Tomcat7,未使用文件的绝对路径和相对路径从Tomcat 7服务器播放视频：编辑摘要：更改了相对路径的示例，我将视频放在应用程序根文件夹中（仍然无法解决视频错误）我们正在为本地使用的视频观看构建一个小型应用程序。由于HTML-5为我们提供了对视频观看的巨大支持，我们选择使用简单的Servlet/JSP编写一个程序，将其部署在Tomcat7Web服务器上应用逻辑如下：根路径（绝对路径）设置为tomcat中我的应用程序的根文件夹根目录中的所有文件和目录都显示在旁边，旁边有一个“go”按钮如果通过单击

编辑摘要：更改了相对路径的示例，我将视频放在应用程序根文件夹中（仍然无法解决视频错误）

我们正在为本地使用的视频观看构建一个小型应用程序。由于HTML-5为我们提供了对视频观看的巨大支持，我们选择使用简单的Servlet/JSP编写一个程序，将其部署在Tomcat7Web服务器上

应用逻辑如下：

根路径（绝对路径）设置为tomcat中我的应用程序的根文件夹

根目录中的所有文件和目录都显示在旁边，旁边有一个“go”按钮

如果通过单击“转到”选择文件夹中的视频文件，则会显示视频查看页面

使用表达式langauge（EL）将视频文件的相对值提供给视频页面，以获得视频标记的源

视频应该从本地主机的硬盘播放到所有浏览器端点

我面临的问题是，我的视频不是从tomcat服务器播放的，而是在浏览器上复制并粘贴到文件时呈现的html“源”代码。视频工作正常。如何让它在tomcat服务器上工作

编辑后：我修改了我的应用程序以调整tomcat myapp根文件夹中的相对路径，但它仍然不工作。下面是经过编辑的问题

我的应用程序的屏幕短片是：
