title: How do I reference libraries in NetBeans?
body: <p>I have a Java Web Services project that was created in an older version of NetBeans, and I haven't accessed it in many months, so my paths and installed libraries are different.</p>
  <p>When I try to open the project, I get a &quot;Resolve Reference Problems&quot; dialog, and two Reference Problems are listed:</p>
  <pre><code>&quot;metro&quot; library could not be found
  &quot;JAX-WS-ENDORSED&quot; library could not be found
  </code></pre>
  <p>I have a fresh installation of <a href="http://www.oracle.com/technetwork/java/javase/downloads/install-jdk6-22nb691-177131.html" rel="noreferrer">JDK 6 Update 25 with NetBeans 7.0</a>, and am running Windows 7.</p>
  <p>What steps can I take to solve this? I don't even know where to start, as every approach I've taken so far hasn't gotten me anywhere.</p>
  <p><strong>Note:</strong> JAX-WS-ENDORSED does not appear in my Libraries listing, so I can't remove it. Something hidden is referencing it.  How would I find this?</p>
