title: Build error in eclipse
body: <p>I am using eclipse HELIOS. I am getting the following error message whenever I build my project.</p>

  <p>Has anyone else experienced such error? Is it a problem of eclipse or the project? It never occured to me before but for this project its happening. It says <code>NullPointerException</code> but that should not pop up such message.</p>
  
  <p>Please help, its driving me nuts. I need to check in my codes but I cant test them due to this building error.</p>
  
  <p>Let me know if more details is reqd.</p>
