Gregory,
I experiment your XSP file (in Cocoon 2.1.8) that handles file uploads from
client using the cocoon file upload support, and I remark that we can't detect
in the code if the size file is greater than the maximum size authorised. But
there is a way, by using a <map:handle-errors> construct in the pipeline :
<map:pipeline>
<map:match pattern="FileUpload">
<map:generate type="serverpages" src="fileupload.xsp"/>
<map:transform src="fileupload.xsl"/>
<map:serialize/>
</map:match>
<map:handle-errors>
<!-- problably a too large file -->
...
</map:handle-errors>
</map:pipeline>
Does anyone see another way ?

Objet : RE: Content length exceeds maximum upload size.
Are you uploading to an XSP or action or what?
I have a couple of XSP examples that might shed some light for you and I have
pasted these here.
Hope this helps mate.

FIRST EXAMPLE
<?xml version="1.0" encoding="ISO-8859-1"?>
<!--

the commons file upload support
The html form requires an enctype="multipart/form-data"
and a

Subject: Content length exceeds maximum upload size.
Hi,
Everytime I try to upload a file that's larger then the configured upload size
I get the following exception.
<map:handle-errors> Does'nt work, the problem looks like this exception is
handled by the servlet itself.
Does enyone know how I get Cocoon not to display this exception?
I'm using Apache 2.1.7
