Webapp not working issue

Hello Everyone, I recently migrated from EA 3 to EA 4, in EA3 i had tomcat 7 with JRE 1.6, when i migrated to EA4 i saw that tomcat 8.5 and JRE 1.8 got installed, since i read in EA4 tomcat is private to each user, i wasn't sure how to make my existing domains which were running on tomcat to work. I searched in internet and found this article i followed it, but still i am not able to get my application running on my domain. dzone.com/articles/deploying-war-file-in-easy-apache-4-tomcat-experim can any of you experts share me the steps that one can do in order to get migrated webapplications work on EA4.
