title: JSF // Primefaces // Buttons not showing.. apple vs windows?
body: <p>I have a mysteroius problem. My classmates and me are programming an project in eclipse with the components java faces, tomcat V9, mySQL, eclipse java EE. So everything was fine since we changed our views into primefaces and a css layout. My mates (working on an apple pc) can run the project without any problems. On our login-page they see the buttons for username + passwort. When I run the login.xhtml I see they css-layout with our logout button and welcome-header but I don't see the commandbuttons (username and password). I am working on a windows pc and have all the components installed that they have. Okay I have to include more JARS (javax.faces-2.2.8 , jstl-1.2, mysql-connector, primefaces-6.0) than they but in the past everything works the same .. 
  In the markers view (eclipse) is no problem showing, in the console are many information tags and some warnings but it seems that there is also everything fine.
  So how could I help you with information that you can fix my problem :p </p>
  
  <p>This is my console output: </p>
