Hello gurus,
I want to use a wizard type of flow where in one screen there is File
Upload. As this is wizard, i was using session scoped formbean with one
property formfile. But seems like formfile is not serializable. What is
proper way of handling this?
Given that a file could be arbitrarily large, is doesn't really make
sense to store it in the session. I'd suggest saving it to temporary
disk and replacing the reference in the form bean with the path to the
temporary file. You can then reload the temp file when your wizard is
ready to deal with it.
So, in your action when the file upload is received, stream it to a temp
file, set the form bean property for the uploaded file to null, and set
another property to the path to the temp file. The form bean should then
serialize without problem, and you can get at the file later when you
need to.
