Hi,
After fresh installation of Odin Plesk (Parallels Plesk a.k.a.) on CentOS 7, Tomcat Java integration was successful. After a while, CentOS 7 community upgraded Tomcat 7 version to 7.0.54-2.el7_1 and the integration is broken now.
Actually it is working somehow. I can deploy .WARs through...
I believe that it is "firewalld" issue.
# systemctl disable firewall.service
is going to allow you to communicate with the server.
After configuring your system, you should configure "firewalld".
