I create account on Johnny, ask about Java, unzip own developed .war-file (works fine on my local Tomcat) and put it to public_html instead of default files. The result is that my servlet don't answer on request. I can access only naked .xhtml page - without further servlet processing. What is a reason of it? Is there a wiki or whatever to read about Java on HelioNet? My account - isabsent.heliohost.org, .war file is on my account. Please, HELP! EDIT: Java hasn't been enabled yet. You must wait at least 24 hours after your request is granted.
