In my opinion a Generator generates xml, an Upload-"Component" instead 
receives xml and stores it whereever wanted.
I thought if it is an UploadTransformer which is controlled by some elements
like e.g. the sql transformer, the upload can be embedded in any xml resource.
The UploadTransformer would find its elements, store the file and replace his
elements with his result element. (This could of course also be done by a taglib
but we *love* Transformers...)

The separation if it is a Generator or Transformer is not very easy, perhaps
it would really be better if it is an Action component. Sorry, I didn't follow 
the thread so I after I woke up now, I go to the mail archive and search there....

Hm, really? Great, than _I_ can sleep even more, if YOU code!
