title: Java EE 6 Eclipse JAX-RS deployment issue
body: <p>I am following a tutorial that shows how to setup JAX-RS. However, I am getting an error when I reach a certain part in the tutorial.</p>
  
  <p>The tutorial is here: <a href="http://www.youtube.com/watch?v=on557289GzA&amp;feature=related" rel="nofollow">http://www.youtube.com/watch?v=on557289GzA&amp;feature=related</a></p>
  
  <p>At one stage it says to perform the following: </p>
  
  <blockquote>
    <p>Click Properties
    -> Click Project Facets
    -> Click JAX-RS(REST Web Service)
    -> Click further configuration
    -> Click OK</p>
  </blockquote>
  
  <p>I then click apply, in the tutorial this should then generate the relevant files, however in my implementation I get the following error:</p>
  
  <blockquote>
    <p>cannot Deploy HelloWorld Deployment
    Error for module: HelloWorld:
    Exception while loading the app :
    java.lang.Exception:
    java.lang.IllegalStateException:
    ContainerBase.addChild: start:
    org.apache.catalina.LifecycleException:
    org.apache.catalina.LifecycleException:
    com.sun.jersey.api.container.ContainerException:
    The ResourceConfig instance does not
    contain any root resource
    classes.%%%EOL%%%</p>
  </blockquote>
  
  <p>I am using a "GlassFish Server Open Source Edition 3 (Java EE 6)" and "Java 1.6.0.22".</p>
  
  <p>Any help in solving this problem would be appreciated.</p>
