title: How do you import a Java Class Library into a Java Web project (using NetBeans)?
body: <p>I've already tried the options "Add folder...", "Add Library...", and "Add JAR/Folder...", but it's not working this time -- I've done this several times before without any problems.</p>
  
  <p>I've also tried to add the folder / JAR file (.war-file) manually to the projects properties in every thinkable way, but still no success.</p>
  
  <p>And so far, Google hasn't helped either..</p>
  
  <p>Any help would really be appreciated.</p>
  
  <p>(This is for a Java Web project with JavaServer Faces, using NetBeans 7.1)</p>

  <p>Solved: I never found out what caused the problem. I ended up re-installing entire NetBeans, and re-created (a thousand times) the project I was trying to import. And in the end, I got it working.</p>
