In JSP, there have servername and path in the form. The form contains enctype="multipart/form-data" and posts to a servlet. The problem is I can't use getParameter or session.getAttribute to retrieve value. So, how can I do? Thanks
getParameter only works with forms posted with the default enctype (URL encoded). When you post a multipart form you either need to parse the request data yourself, or use some 3rd party software to do it. I know this has been discussed many tmes here and in the JSP forum. A little searching may find what you are looking for.
