title: How do I reference classes from another project in NetBeans?
body: <p>I am using NetBeans 6.8. </p>
  
  <p>I have a class <code>ClassA</code> situated in <code>PackageA</code> in <code>JavaApplicationProject1</code>.</p>
  
  <p>I plan to use this class in <code>ClassB</code> situated in <code>PackageB</code> in <code>JavaApplicationProject2</code> just by importing it. One option is to copy <code>ClassA</code> in <code>PackageB</code>, but I don't want to copy. How can I do this?</p>
