There is no :: example of use of this package or I didn't found them... :: :: Do you know any links which permits me to solve my problem of servlet? :: (Links with complete examples like servlet code and/or form code) :: :: And other question, I didn't understand your last reported problem. Does it :: mean I must use a "response.sendRedirect()" instead of a :: "request.sendRedirect()" ? :: :: I hope you could help me, as you surely guess I am a newbie in the jsp and :: servlet world so I try to learn a maximum of things. :: :: Nevertheless, I thank you for your time... :: :: Florian Kiebel :: :: -----Message d'origine----- :: De�: Martin Cooper [mailto:[EMAIL PROTECTED] :: Envoy�: lundi 31 mai 2004 19:28 :: ��: Jakarta Commons Users List :: Objet�: Re: [FileUpload] Problems with chaining uploading :: :: Why, oh why, do so many people insist on using JSP pages for binary :: request handling that should be in a servlet... :: :: Anyway, I see two related problems (apart from the fact that the code :: should be in a servlet). :: :: 1) Redirecting POST requests is generally disallowed, and is specifically :: disallowed by the HTTP spec without explicit confirmation from the end :: user. :: :: 2) You are writing to the response, and then redirecting the request.
