Question

我一直在使用Eclipse IDE和Tomcat v7.0。到昨天为止一切正常。即使是jsp文件也可以正常执行，因此在代码中没有错误。早些时候，当我遇到这样的错误时，我更改了端口号，清理了服务器并投影了它的工作原理。但是这次，我使用这些论坛尝试了以下方法

1）我在Google上尝试了所有功能。

2）更改了端口号。

3）更改服务器位置。

4）删除目录中的.snap文件。

5）多次重新安装了tomcat。

6）清理了项目和服务器。

7）更改了tomcat的版本，但未检测到。

我尝试更改属性和所有内容。它说no tcnative-1 in library path，所以我重新安装了三次。我不知道该怎么办必须在3周内提交项目，而我被困了。

有人可以告诉我还有什么事吗？
