Tomcat v7.0 server failed to start

Question

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.

But when I try to start the server, this is what happens:

NOTE: I do not have a servlet-api.jar in my WEB-INF/lib

There the problem is a wrong servlet-mapping. I do not have any servlets — Ivar Reukers, Sep 29 '15 at 07:28

check {TOMCAT_HOME}/logs/catalina.out for 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

Delete existing server in the "Servers" view (tab) of eclipse.

Also delete servers folder in navigator/project explorer in eclipse.

Recreate server, it worked for me.

Do you have anything deployed on the server while are you starting it? Try this:

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.

In eclipse double click and open server. open Modules view.

List of web modules can be seen.

Remove unnecessary modules, save and retry.
