  Subject: GetParameter()-IllegalArgumentException


  Hello,
    I know that getParameter() can be used to access the data from the
  requested page.  And even know that this will not be of very much help
when
  used with doPost() as it can read the data only once.
    I have used a simple class to connect to Servlet through URLConnection.
  I've used service method in the servlet.  I am using getParameter(..)
method
  to access a member variable from the simple class.  But it is throwing
  ***IllegalArgumentException***?

  Can't I use this method with simple class and servlet?  Please let me know
  if there's something wrong in it.....


  Thanks in advance,
  Ashwini
