Question

我有一个在我的prod服务器Tomcat 7中运行良好的基础项目。

我在Eclipse中导入它，创建了一个tomcat 7服务器来运行它并进行了一些开发。在Eclipse浏览器中一切正常，但是当我导出war文件并将其放在我的prod服务器上的webapps文件夹中时，我收到以下错误：

FAIL - Application at context path /art_current could not be started

有关信息，我的Prod tomcat在Java7下，所以我在1.7中更改了我的项目构建路径和java编译器。

我尝试在META-INF文件夹中创建一个context.xml文件：

<Context path="/art_current" />

但仍然会出现同样的错误

我注意到了一些事情，当我通过Eclipse导出我的项目时，项目结构被改变了：

基础项目：

从Eclipse导出的项目：

正如我们所看到的，有一些新文件夹，特别是 META-INF 文件夹出现，这是正常的吗？

也许我做错了什么但我找不到什么

修改

这是我尝试从tomcat管理器启动应用程序时得到的日志：

Answer 1

我找到了以下解决方案：

在日志文件中我们可以看到：

Unsupported major.minor version 52.0

正如我们在此处所见：Unsupported major.minor version 52.0

这是因为我的eclipse在Java 1.8中编译了我的项目，我的tomcat在1.7中运行。即使我在Eclipse下改变了我的项目构建路径和编译器（+ clean and rebuild）。

所以我只是将我的Tomcat java版本从1.7切换到1.8，现在一切正常。

来自eclipse的tomcat 7项目
