Webinf/lib folder missing caused error 500 and 404 in servlets

Question

Why am I getting the Error instantiating servlet class error? It was working fine until I added a main page.

I have tried cleaning project and serer and rebuilding. Doesn't work. The path seems okay. Can't figure out why.

The error on the web browser

Web page error

When I go back and click on submit, I get the 404 error.

HTTP Status 404 -
type Status report
message
description The requested resource is not available.

I'm using Apache Tomcat/7.0.47 and Eclipse IDE

My folder structure:

Answer 1

I had a problem with my libraries. Went to the problems view on my eclipse and fixed problems in my project. Deleted my jars from all folders, imported them into the webinf/lib folder and added them to my build path. There was nothing wrong wit the code apparently.
