Anna,
What does your C:\ms4w\Apache\logs\tinows.log file contain ?
Also yeah you should use --post-data='<wfs:GetFeature...' and not
--post-data="<wfs:GetFeature...". If your dataset isn't too big, you
could remove the <ogc:Filter> node. Also, try replacing
xmlns:feature="http://127.0.0.1/" by xmlns:tows="http://127.0.0.1/".
HTH,
Alexandre
