Hi, Winston.
I try to resolve my problem with character enoding. It seems I found a culprit: It is FileUpload component. I have already posted in http://forum.sun.com/jive/thread.jspa?threadID=106660&tstart=0
There is post with problem alike

So if it is really a bug, how can I hande character enoding? Assuming, in worst case, page encoding is UTF-8, client locale encoding always is Cyrillic Windows-1251 (stardard de-facto in Russia) ? And I need to save data into Oracle database with CL8MSWIN1251 encoding.
