My dynamic project is not able to start the tomcat server. It always gives the same pop-up saying failed to start the service. I use Apache Tomcat v 7.0.6 and jdk8 and eclipse 2019-09.
Following is the error trace that I get.

Things to note :
When I run Apache tomcat use executable file, http://localhost:8080 is working.
I downloaded a sample dynamic project and its working fine i.e. tomcat server is starting perfectly.
Also, I tried reinstalling eclipse, jdk, tomcat, still same problem I have seen other questions and followed the solutions but none solved my problem.
