Answer 1

It seems that your schema.xml file references stop word files that are missing from the /conf folder. Open your schema.xml file and search for stopwords in it. Find the references and see if you're missing any. If so, simply copy missing files to your /conf folder. Some of them could be located in /conf/lang directory.
As a side note, consider using forward slashes ('/') for paths in your configuration files. You can avoid many problems by following that rule with Java apps.
