title: Eclipse unknown java object
body: <p>So I'm trying to bring some java files from a prior project into a new project (by copying and pasting them to the new project's directory through the file system and refreshing through Eclipse) and I keep getting this little blue question mark underneath the files I'm bringing in (which apparently means that the file is an unknown object). </p>
  
  <p>(Here's an image of what I'm talking about: <a href="http://i.imgur.com/dSa24dk.png" rel="nofollow">http://i.imgur.com/dSa24dk.png</a>)</p>
  
  <p>For context, both of the projects have different functionalities. The old one responds to REST calls (for which a web.xml (which is also not recognized by Eclipse) was used) and this new one uses Hibernate. </p>
  
  <p>How can I make Eclipse recognize files from the previous project?</p>
