Thread: "Run as server" doesn't work in JEE

On my Mac 10.11.3 I've installed the Eclipse JEE IDE (Version: Neon.3
Release (4.6.3))
I also installed apache-tomcat 9 on my Mac, using the following commands :

sudo mkdir -p /usr/local
sudo mv ~/Downloads/apache-tomcat-9.0.0.M21 /usr/local
sudo rm-f /Library/Tomcat
sudo ln -s /usr/local/apache-tomcat-9.0.0.M21/ /Library/Tomcat
sudo chown -R roparzhhemon /Library/Tomcat
sudo chmod +x /Library/Tomcat/bin/*.sh

When I try "Run as server" on a minimal html file in JEE, I get the following
error message :

Could not load the Tomcat server configuration at /Servers/Tomcat v9.0 Sever
at localhost-config. The configuration may be corrupt or incomplete.

Any help appreciated.

Deployment of applications on Java EE Application Servers or containers is possible only when you have WTP installed. From the screenshots posted, I can infer that either WTP is unavailable or it hasn't been loaded by Eclipse (for some unfortunate reason).
