“unsupported collating sort order” when trying to read from Access using Jackcess (Java)

Question

Answer 1

Jackcess only supports indexes on Text fields in an Access database when the database is using the "General" sort order (ref: here).

According to the related Microsoft Office support page:

To reset the sort order for an existing database, select the language you want to use and then run a compact operation on the database.

So, for Access 2010 that would presumably mean selecting File > Options from the Access ribbon bar, choosing "General" or "General - Legacy" for the "New database sort order" on the "General" tab, ...

... then performing a "Compact and Repair" on the database.

Note: If Windows is using a non-English locale then the procedure described above might not rectify the problem. See this answer for details.
