I think she is missing as to where tmp.xml should be kept within her bigdata/Ant folder as I think bigdata is not able to find tmp.xml.
Alice I think you should keep tmp.xml within the bigdata folder which you downloaded.

in java script in your browser client. That choice does not effect other workbench clients and does not
effect the behavior of the various endpoints when using command line tools to query or update data in the database. Thus your command line requests are being made against a namespace that is not configured for RDR support.If you want to address a non-default bigdata namespace using curl or wget, you must use the appropriate URL for that namespace. This is all described on wiki.bigdata.com on the page for the nanoSparqlServer in the section on multi-tenancy.
