title: Tomcat7 ubuntu user owner
body: <p>By default settings on Ubuntu tomcat7 runs under 'tomcat7' user and group.
  I want to change it, cause I can't upload via sftp files to the directories, which are created by 'tomcat7' process.</p>
  
  <p>Changing TOMCAT7_USER TOMCAT7_GROUP in /etc/init.d/tomcat7 and restarting the service doesn't help..</p>
