Hi Daniel,

When you specify a local DwcA Load the archive needs to be unzipped. Try unzipping 2f676abc-4503-489e-8f0c-fcb6e1bc554b.zip and then running the following:
sudo java -cp .:biocache.jar au.org.ala.util.DwCALoader dr7 -l /data/collectory/upload/1398658607824/2f676abc-4503-489e-8f0c-fcb6e1bc554b

If you configure the collectory to provide the dwca the biocache automatically unzips the archive for you.  You would need to configure dr7 with the following connection parameters:

"protocol":"DwCA"
"termsForUniqueKey":["occurrenceID"],
"url":"file:////data/collectory/upload/1398658607824/2f676abc-4503-489e-8f0c-fcb6e1bc554b.zip"

You could then load the resource by:
sudo java -cp .:biocache.jar au.org.ala.util.DwCALoader dr7

If you continue to have issues please let us know. 

Hope that this helps.

Regards
Natasha

Subject: [Ala-portal] DwC-A loading problems

Hi Nick and Dave,

We are having some problems in Biocache during the upload of DwC-A files.

As shown below, after run the method "au.org.ala.util.DwCALoader", our system returns the error message "Exception in thread "main" org.gbif.dwc.text.UnkownDelimitersException: Unable to detect field delimiter"

I accomplished tests using DwC-A files with tab-delimited text files and comma-delimited text files. In both cases the error generated was the same.

What causes these problems? (** CSV Loader works great)
