Access denied or FileNotFoundException during file upload

Have you experienced "Access denied" or "java.io.FileNotFoundException" during a file upload (for example a CSV datastore)? Problem can be in permissions that need to be changed. DataCleaner Monitor temporary upload directory is probably not writable. Typical situation like this can happen on Windows if you unzip your Apache Tomcat into "Program Files" folder.

Workaround

You can fix this by using proper Windows installer for your Apache Tomcat and/or putting it somewhere else than "Program Files". Another approach might be a manual change of permissions so that the temporary file upload folder is writable.
