I will try the filter, and let you know -- I don't think that Struts is too
worried about
the encoding, while debugging, I saw that things go wrong much earlier,
"above"
struts, in the regular servlet layer on which Struts Action sits...

Thanks for the suggestion..  You know, it is really disappointing, that one
has
to do "custom programming" (filter) depending on what kind of a container
engine is
used - in the ideal world, this should just work for all different
application servers..
God only knows, what if anything I would have to do for Websphere, Weblogic=
,
Oracle server etc...

Thanks for your help.

Alex.
