title: Your active platform is: JDK_1.6, but the corresponding property "platforms.JDK_1.6.home" is not found in the project's properties files
body: <p>I'm a Java noob (but have been programming for 25+ years, and have worked with OO languages from day 1).</p>
  
  <p>All of a sudden I started getting this error:</p>
  
  <pre><code>Your active platform is: JDK_1.6, but the corresponding property "platforms.JDK_1.6.home" is not found in the project's properties files. 
  </code></pre>
  
  <p>Not sure what caused this condition, and not sure what Java's asking me to do. I'm working in the NetBeans IDE. The last thing I attempted to do is add some binary (image) resources to my project.</p>
