    Exclamation Get session attributes in servlet while using multiplart/form-data tag is JSP

    Hi,
    I am trying to upload a file onto some location and the logic for the same is working fine. i.e the file is getting uploaded.
    I have two JSP files one where i have browse button and other with the upload logic. When I click on browse and select the file to be uploaded and submit the request, the file gets uploaded but I am not able to get the session attributes of previous JSP in the new JSP by writing request.getParameter("first"); It is returning null.

    Default thats so obvious!

    Obviously request.getParameter will return null. when u use enctype="multipart/form-data", the content is transmitted as a MIME stream. Request.getParameter doesn't work with MIME streams. Either u upload the file in a separate form, or use apache's/OReily's file upload library, bcoz its very very tough to xtract datas from boundaries.

    For more details, search this forum, u'll get a lot of post on uploading file!

    good luck!

    Yep.
    Use one of those file upload libraries...and stick the logic in a Servlet, not a JSP.
