getParameter ... called after reading... ServletInputStream

[Stefan Groschupf <sg...@media-style.com>]

Hi,
I have trouble using the file upload.
Small uploads working  but with an error message
One of the getParameter family of methods called after reading from the  
ServletInputStream. Not merging post parameters.>

In case i try bigger uploads I got this exception:

Failed to parse multipart request:
org.apache.commons.fileupload.FileUploadException: Processing of  
multipart/form-data request failed. EOF after reading only: '284672'  
of: '16730758' promised bytes, out of which at least: '3280' were  
already buffered

I found only one posting that where the responder suggest do not use  
any getParameter call after readting the formFile.getInputStream.
I do not call such method after getting the input stream. May someone  
can give me a hint what I may doing wrong?
I figure out that all people had this problem was using weblogic, is it  
may a weblogic bug?

Thanks you!
Stefan
