Here is my servlet code. My objective is that according to the request the
servlet will do something specific as you can see... This way i get no
problems , get and post request are recognize correctly. However i need to
pass one more parameter in the post request so i cannot use just the
getQueryString() method...
Richard, i hope this helps you in trying to resolve my problem... Thanks for
your help

Subject: Re: getParameter()
Hugo,
Are you calling getInputStream() or getReader() in the servlet, if so, it
will interfere with the results of the getParameter() method. It would
help if you sent your servlet code.
