Here is the Action I use. It is based on the example in the Cocoon Developer's Handbook.
Hopefully I copied and pasted it w/o error.
The sitemap would be:
in map:components section with the other actions:
<map:action logger="sitemap.action.fileupload" name="fileupload"
src="yourpackagenamehere.FileUploadAction" />in your pipeline section
<map:match pattern="do-upload">
<map:act type="request">
<map:parameter name="parameters" value="true" />
<map:act type="fileupload">
<map:parameter name="upload-dir"
value="incoming" />
<map:generate src="success.xml"/>
<map:serialize type="html"/>
</map:act>
<map:generate src="uploadfailed.xml" />
<map:serialize type="html" />
</map:act>
</map:match>HTH Steve

Hi again Geoff...
I'm still trying to implement the code in order to upload files with cocoon.
I have readed wiki web a thousand times ... ;-) ..
