Install Tomcat on Ubuntu
Help you install tomcat and start using this webserver on Ubuntu. First, the JDK needs to be installed first in order to install tomcat. If you don’t have JDK installed then start by installing JDK or if you have it already installed then skip the JDK installation step. If you don’t know whether JDK is installed on your system or not then you can simply run this command in terminal:
$ javac
If it results in error, it means that there is no JDK installed. If JDK is not installed on your system then you can install it by using the following command in terminal:
$ sudo apt-get install openjdk-12-jdk
