SOLVED Tomcat showing just blank page

I've installed tomcat85 under easyapache4, activated tomcat for the user, and when opening account's [domain.tld]:10000 it loads a blank page, I can see from tomcat logs under accounts home folder
ea-tomcat85/logs/ that it is running. Testing out
ubic stop/start ea-tomcat85 seems to work and when stopped the connection to port is rejected.

How can I get anything else like manager/html to show up?

 

It turns out that white page is ok, it's just that ea-tomcat85 doesn't come with manager installed and you have to set up an application otherwise it will just not work - showing 404 in tomcat log.
