title: eclipse for java- how to add support for jsf 2.1 to eclipse 3.7-indigo
body: <p>I was working on a JSF 2.1 project in Eclipse 4.2 (Juno)- however I needed to use a plugin which has not been updated to work in Eclipse 4.2- so I installed Eclipse 3.7-Indigo and tried opening the JSF project in Eclipse Indigo.</p>
  
  <p>However this is the error message I am getting -- </p>
  
  <pre><code>Implementation of version 2.1 of project facet jst.jsf could not be found. Functionality will be limited.    
  </code></pre>
  
  <p>How do I fix this problem? The project I am using utilises JSF 2.1 and PrimeFaces.</p>
