JetS3t
includes a mime.types file in the classpath root.
This is the file Synchronize expects to find in the classpath,
is this file present in your configs directory? If not, you may need to replace it.
If you don't wish to use the mime.types file to guess the mimetype of your files, you can get rid of the warning message by changing the following line in
log4j.properties:
log4j.logger.org.jets3t.service.utils.Mimetypes=INFO
to read:
log4j.logger.org.jets3t.service.utils.Mimetypes=ERROR
