Hi Felix,
thanks for the reply.
I switched to using request.getRequestParameterMap() in my POST.jsp, but
nothing changed and the error is the same. After inspecting the stack
trace and my repository again I think the error occurs when Sling tries
to read the input and build the request parameter map, because my script
is never compiled or executed (at least there is no compiled class in
the repository).
To verify this I used an simple POST.jsp that just outputs a plain
string and does not access any parameters. When I post my file I get the
same exception.
Regards,
Alex

Hi Alexander,
If you upload the file with a multipart/form-data POST, Sling will
already have read the input and will provide the data in the
RequestParameterMap as RequestParameter instances, which allow you
access to the uploaded file data.
Hope, this helps.
Regards
Felix

Hi all,
I have a problem with the file upload in Sling. I have a form that
uploads a file and an according POST.jsp for handling the upload. The
log shows that POST.jsp is resolved correct, but when I try to upload
the file, I get the following exception:

Seems like somebody is calling getReader() before ParameterSupport code
is executed. But I was not able to figure out where this happens.
Any ideas?
