File Uploads
Hi!!
I want upload files in a simple form, but I don´t know to modifie the
upload-directory because I write "pfc/uploads" in the file web.xml and the
form doesn't upload.
What is the configuration of the parameters in web.xml? I want to use
pfc/uploads that upload-directory
Thank you.
Miguel Ángel

it works! your 'copy file to correct directory and delete from incoming'
looked similar to my code and that made me look for the mistake at other
places... found it.
dankeschön and till next

I believe, this rename function is only working since JDK 1.4. so if you
need to use an earlier version, you have to write this by yourself
eventually.

My solution is basically working like this:
(1) set the parameters in the web.xml (I guess), so that file uploads
are automatically accepted and enter the path where they should be put to.
(2) I have a form, where you may enter data of a publication (author,
title, ...) plus a pdf document.
(3) the following xsp gets the pdf filename adds some timestamp to
ensure, that the filename is unique, than creates a SQL insert and
inserts the metainformation including filename into the database, then
moves the PDF from the "general" incoming directory to the desired pdf
directory:
so this is the xsp. maybe it is helpful for you.

hi geoff,
i've seen the wiki pages and also the FileUploadAction in the
Developer's Handbook (Moczar/Aston). my problem is that i don't want to
put all the files into one directory but put them into the directory
named after a project that is to be choosen in a select field (is that
understandable?). there is a directory for every project and the file
belongs to exactly one project. therefore the way suggested by alexander
seemed quite appealing to me.
btw i need this for an app written in 2.0.4
thanx juliane

There is good information about this at the wiki. Go to wiki.cocoondev.org
and search for upload.
Geoff
upload-directory does not have to be under WEB-INF - it can be relative or
absolute anywhere on your system. relative paths are resolved from the
servlet context - which is the main directory of cocoon.

I'd recommend doing this with an action. The wiki covers this
pretty well (though it's clearer if you're using 2.0.x).
Check out:
http://wiki.cocoondev.org/Wiki.jsp?page=FileUploadsWithCocoon
http://wiki.cocoondev.org/Wiki.jsp?page=FileUploadWithAction
and http://wiki.cocoondev.org/Wiki.jsp?page=FileUploadsWithFlow
if you're using 2.1 (even if you don't use flow, this contains
useful info for the changes to the upload api in 2.1)

well, I changed the parameter in the WEB-INF/web.xml:
<init-param>
<param-name>upload-directory</param-name>
<param-value>WEB-INF/work/upload-dir</param-value>
</init-param>
and it works, but I am not sure, whether this directory has to be below
WEB-INF?
however, one general remark: you must not forget, that this is a general
setting for *all* Cocoon applications. So what I do is, that is set the
directory as mentioned above, and in the cocoon application I use an XSP
file to move an uploaded file into the projects destination directory,
which seems to work pretty good and is rather easy to implement.
If you like, I could provide this XSP for you.

Which cocoon version? This makes a lot of difference with
configuration.
