Tomcat v7.0 server failed to start
提问by Ivar Reukers
So, I'm trying to work with a tomcat v7.0 server. I have already worked with a tomcat v8.0 server but because hosting providers don't support tomcat v8.0 I need to create a v7.0 project.
所以，我正在尝试使用 tomcat v7.0 服务器。我已经使用了 tomcat v8.0 服务器，但是因为托管服务提供商不支持 tomcat v8.0，所以我需要创建一个 v7.0 项目。
But when I try to start the server, this is what happens:
但是当我尝试启动服务器时，会发生以下情况：
NOTE: I do not have a servlet-api.jar in my WEB-INF/lib

check {TOMCAT_HOME}/logs/catalina.outfor more possible errors in this scenario. I think this is because of the wrong configurations in server-config. Previously you have used the tomcat 8 then it will still have the previous configurations. So clean full project and remove all the servers then start with Tomcat 7.0
检查{TOMCAT_HOME}/logs/catalina.out在这种情况下更多可能的错误。我认为这是因为 server-config 中的配置错误。以前你用过tomcat 8，那么它还是以前的配置。所以清理整个项目并删除所有服务器然后从Tomcat 7.0开始

Do you have anything deployed on the server while are you starting it? Try this:
您在启动服务器时是否在服务器上部署了任何内容？尝试这个：
- Right click on the server/Add and remove...
- Remove every project from server and click ok.
- Right click on the server/Clean.
- Start the server again.
- 右键单击服务器/添加并删除...
- 从服务器中删除每个项目，然后单击确定。
- 右键单击服务器/清理。
- 再次启动服务器。
