how to remove tomcat8 from kubuntu 14.04

Question

I have installed tomcat8 to using instructions from this website https://www.digitalocean.com/community/tutorials/how-to-install-apache-tomcat-8-on-ubuntu-14-04 But now I can't set up server in netbeans IDE for this tomcat8. I have researched ubuntu forum and found out I have to have tomcat7 to successfully running in netbeans.

P.S. I have installed tomcat7 from ubuntu repo but it failed to start. I think because tomcat8 doesn't allow it to do. Thank you for any help in advance.

Solution

Reverse the installation via if you have used these steps to install tomcat8

sudo initctl stop tomcat
sudo rm -r /opt/tomcat
sudo rm /etc/init/tomcat.conf
sudo initctl reload-configuration

Now, to be sure, install tomcat7 again.
