title: Netbeans 6.9.1 installation error : "No compatible JDK was found."
body: <p>I'm trying to install Netbeans 6.9.1 in my Ubuntu 9.04.</p>
  
  <p>But when i run the script 
   <code>./netbeans-6.9.1-ml-linux.sh</code>, the installer GUI displays the error "No compatible JDK was found.",
  and in the next window it asks for the installed JDK path.
  What can I do to get it to install?</p>
