Dear Filip,
 
That solves it, many many thanks.
 
Just a comment if others went into same problem:
* request.setCharacterEncoding("ISO-8859-1"); does not solve the problem
* getBytes() is not deprecated, it uses the platform's default charset instead.
 
Thanks again,
Ahmed Ashour

Filip Hanik - Dev Lists <devlists@(protected):
getBytes() is deprecated for the reason that different VMs/OSs have
different default encoding.
could that be the cause of your problem?

what if you try getBytes("ISO-8859-1") on both platforms, do you still
get diff results?

Filip
