Oskar,
The
org.apache.cocoon.component.request.multipart.MultipartParser
will create either a FilePartFile (which is the file
"part" of the request parsed out and saved to disk) or
a FilePartArray (same thing, but kept in mem as a
byte[]) for you automatically before the pipeline
enters the picture. To get it to make the Array,
configure autosave-uploads in web.xml to false, like
so:
<init-param>
<param-name>autosave-uploads</param-name>
<param-value>false</param-value>
</init-param>
If that entry doesn't exist in your web.xml, you need
to get updated source from cvs - this is a recent
change. I'm pretty sure that the change is available
in 2.0.3 as well as 2.1 (which one are you using?)
You can also just delete the FilePartFile after you're
finished with it. I think it exposes a File getFile()
method which you can use. In the long run, it doesn't
matter whether it was saved temporarily to disk or not
(unless there's a performance benefit one way or the
other).
Good luck,
Geoff
