if (ServletFileUpload.isMultipartContent(request))
{
final FileItemFactory factory = new DiskFileItemFactory();
final ServletFileUpload fileUpload = new ServletFileUpload(factory);
try
{
System.out.println("t ");
/*

*/
final List items = fileUpload.parseRequest(request);
if (items != null)
{
final Iterator iter = items.iterator();
while (iter.hasNext())

System.out.println("Field Name: " + fieldName + ", Field Value: " + fieldValue);

}
else
{
final File savedFile = new File(FILE_UPLOAD_PATH + File.separator

System.out.println("Saving the file: " + savedFile.getName());
item.write(savedFile);
}
}
}
}
catch (FileUploadException fue)

fue.printStackTrace();
}
