  <p>When i execute in java project using eclipse it work fine...
  But when i execute using web application and in this i call it from controller page like</p>
  
  <blockquote>
    <p>DicomToJpeg.dicomToJpeg("d:/F74AFBC7");</p>
  </blockquote>
  
  <p>then it gives error like...</p>
  
  <pre><code>java.util.NoSuchElementException

  <p>How to solve this error please help me....</p>
