title: Cannot add a project to a Tomcat server in Eclipse
body: <p>I cannot add my project to a server in Eclipse - why is that?</p>
  <p>I installed all necessary tools (Web Dev, Java EE, Server Adapters, and Tomcat itself, everything)</p>
  <p>I configured the runtime environments, adjusted all Java Versions to JDK 6 (because it should run on Tomcat 6), but still the left side of the dialogue where I could add resources is empty when creating a new server.</p>
  <p>What else could I try?</p>
  <p>PS: I am using <a href="https://en.wikipedia.org/wiki/Eclipse_%28software%29#Releases" rel="noreferrer">Eclipse v4.2</a> (Juno) on Windows 7 Professional.</p>
