I'm not exactly sure I've followed what you're trying
to do, but are you aware that multipart requests are
handled automatically by cocoon? When a file is
included in a request, the default behaviour is to
save it to upload-dir under the work directory in
whatever servlet container you're using. In tomcat,
this means
$TOMCAT_HOME/work/Standalone/localhost/cocoon/cocoon-files/upload-dir
In addition, an
org.apache.cocoon.components.request.multipart.FilePartFile
(or FilePartArray - both extend FilePart depending on
behaviour - see javadocs for info) object is placed in
the request and can be retrieved by any cocoon
component with a reference to the request. FilePart
defines a method to get the contents of the file as an
InputStream. From there you can move it elsewhere on
disk, put it in a database, or parse it and send the
sax events down the line, as it sounds like you want
to do.
