/**
 * Example of how to get useful things with the uploaded file structure.
  * Generally speaking, this method should be overrided by framework's users.
 * /*w w  w  .j a v a 2  s .  c  om*/
 * <p>Here we demostrate how to extract useful infos 
 * (<code>name, value, isInMemory, size, etc) </code>)
 * plus how to deal with memory- or disk-persisted cases.
 * 
 * <li><p>We pass the whole <code>FileItem</code> structure
 * to the next <code>jsp</code> page, which gains the ability to extract 
 * infos as well: via Request, under name: "file-" + fieldname
 * 
 * <li><p>The file content can be retrieved here or later, <code>FileItem</code>
 * object can use its data-getters in <code>.jsp</code>s! 
 * <p>In this code, we retrieve file content and pass it in Request 
 * for next uses under the a general format of 
 * array of bytes (<code>byte []</code>);  with name equal to "file-" + fieldname.  
 *  
 * @param pItem
 * @throws IOException
